The material of the china 2mm aluminium sheet is usually 1000, 2000, 3000, 5000, 6000 and 7000 series aluminum alloys. The 2mm aluminium sheet is a common seen 4x8 Aluminum Sheet thickness, and the thickness range of aluminium sheet product is usually 1-300mm. The allowable thickness tolerance of the national standard aluminum sheet is plus or minus 0.02mm. The price of the china 2mm aluminum sheet depends on the alloy grade, temper, the size is different, the price is also different.

There are many specifications and models of aluminum sheet materials, and they are widely used. Among the product quality of aluminium sheet, the thickness control can be an evidence to prove the strength of the aluminium sheet manufacturer. The allowable deviation of the china 2mm aluminium sheet needs to be determined according to the width of the aluminum sheet:

Width (mm) Thickness tolerance (mm)

400～600 ±0.15

600~800 ±0.20

800~1000 ±0.20

1000~1220 ±0.24

The china 2mm aluminium sheet belongs to thin aluminum sheet product, 3mm, Aluminum Sheet 5mm, 6mm and 8mm are also the common used thickness. The thin aluminium sheet is processed by rolling processing, include cold rolling and hot rolling. Medium thick aluminum plates must be cut with large sawing equipment in production tolerances, so the width and length tolerances usually require a 5mm allowance. Compared with thin aluminum sheets, the tolerance of precision leveling machines is small, but for medium thick aluminum plates cannot be leveled. Only large sawing equipment should be used. In terms of thickness tolerance, our company can control it at around 0.1mm. Usually, the medium and thick aluminum plate is a mold, which is needed for mechanical parts and needs to be milled later, so our company usually goes to the tolerance range.

Aluminum plate products are rectangular plates rolled from aluminum ingots, which are divided into pure aluminum plates, alloy aluminum plates, thin aluminum plates, medium-thick aluminum plates and aluminum checkered plates. 4×8 aluminum plate is a common aluminum plate size, and the grades of aluminum plate 408 are 1050, 1060, 1070, 1100, 3003, 3004, 3104, 3105, 5052, 5083, 5086, 5454, 5754, 6061, 6063, 7075 and 8011.

How to distinguish the quality of 4x8 aluminum sheet metal?

1. Check whether the aluminum plate metal has obvious deformation, and check the appearance of the 1 8 aluminum sheet. There should be no protrusions or protrusions. Whether the surface is smooth and flat, whether there are cracks or discs, scratches, burrs, if found, it is best not to buy.

2. Carefully check whether the surface color of the 4x8 aluminum sheet has different shades of color. The color difference indicates that the quality is not high. Of course, contour lines of the same type can also be combined for comparison. Of course, if the color difference is too obvious, it is best not to buy it. Check whether the section thickness of the alloy aluminum plate is the same as the model.

3. You can scratch the metal surface of the aluminum sheet with a smooth hard object, leaving white scratches. Lightly wipe the aluminum plate alloy and observe by hand. If it cannot be wiped off, the material may have quality problems, but if it can be wiped off easily, the oxide film thickness on the contoured surface is acceptable.

6061 t6 aluminum alloy plate has three different common heat treatment states: O, T4 and t6. The difference between the state of 6061 o aluminum sheet T6 and T651 is that in general, the internal stress of T6 will be relatively large, and the processing will be deformed. 6061 T651 should be a more suitable processing state, which is stretched on the basis of the T6 state to eliminate internal stress. The hardness of 6061 aluminum alloy plate has a lot to do with its composition. The higher the magnesium content, the better the hardness.

The main alloying elements of 6061 t6 aluminum alloy sheet are magnesium and silicon, and form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the adverse effects of iron. Small amounts of copper or zinc are sometimes added to increase the strength of the alloy without significantly reducing its corrosion resistance. There is a small amount of conductive material to counteract the detrimental effects of titanium and iron on conductivity. The zirconium or titanium in the 6061 aluminum plate can refine the grains and control the recrystallization structure. To improve machinability, lead and bismuth may be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial age hardening function.

6061 t6 aluminum alloy sheet has good processing performance, good corrosion resistance, high toughness, easy coloring after processing, and good oxidation effect. The main uses of 4 x 8 aluminum sheet are: widely used in various industrial structural parts that require a certain strength and high corrosion resistance, such as the manufacture of trucks, tower buildings, ships, trams and railway vehicles. 6061 Aluminum Alloy Material & # 8217; Proprietary chemistry, casting and production techniques are the stability and consistency of the material. High stability and consistency, reducing deformation and movement during sawing and machining.

 

Today marks the 27th anniversary of the launch of the Hubble Space Telescope, which has made outstanding contributions to human scientific research in space. What are the applications of 4x8 aluminum sheet in the Hubble Space Telescope?

aluminum sheet

For the Hubble Space Telescope, mirrors are very important. The mirror-polished coating of the telescope uses an aluminum plate with a thickness of 75 nm as a reflector. Lightweight aluminum sheets are used as the telescope's instrument and housing. The application of aluminum plates in the Hubble Space Telescope is characterized by strong reflectivity and light weight. Aluminum sheets are usually used for aluminum sheets: lighting, solar reflectors, building exteriors, interior decoration, ceilings, walls, furniture, cabinets, elevators, signs, nameplates, luggage, interior and exterior car decoration, home appliances, aerospace and military. Today we will talk about the application of aluminum sheet in the aviation field. At present, the total amount of aluminum in the aerospace field accounts for about 5% of the total aluminum consumption worldwide. However, due to the large consumption of aluminum sheets in the aerospace field and the high technical content of aluminum, this field has become a hot spot for aluminum companies. . The C919 aircraft project uses medium and Thin Aluminum Sheet, and the products are mainly 7 series aluminum alloys. The requirements for aluminum plates in the aerospace field are not only reflected in the characteristics of high metallurgical quality, high performance technical indicators and specifications, and complex dimensions, but also in their structure, performance, surface accuracy, especially strength, plasticity, corrosion resistance and fatigue resistance. The performance is extremely strict requirements. 7005 and 7075 aluminum alloy sheets are the highest level products in the aeros pace field 7 series of aluminum alloys, and the heat treatment process can be improved. For example, 7075 aluminum plate has high strength (high temperature strength and low temperature strength are better than other aluminum alloys), and it has good plasticity after solution treatment, so it has excellent comprehensive mechanical properties. 7075 aluminum is mainly used to manufacture high-strength, high-corrosion-resistant high-stress plane structures, such as the upper and lower wing sidewall panels and purlins of aircraft. At present, the global consumption of aviation aluminum alloy sheets is estimated to be 780,000 tons, and it is estimated that by 2020, the global aviation aluminum sheet will be 1 million tons.

Thin aluminum sheets are used in the lighting industry for their light weight, low cost, long life and high quality. Sheet aluminum manufacturers have many customers who manufacture aluminum lamps, lamp shades, circuit boards, and more. Sheet aluminum has 1060, 1070, 1100, 3003 and 5052 alloys. The following describes the application of thin aluminum sheets in this regard.

Application range of thin aluminum sheet in lighting:

1. Aluminum plate 3104 is used as lamp sockets for incandescent lamps and fluorescent lamps, and other thin aluminum plate materials have become routinely used as sockets.

2. Casting, stamping and spinning aluminum parts are often used for artistic decoration of lamps such as table lamps and floor lamps.

Aluminum plate reflectors are common for fluorescent lighting systems and other lighting installations.

4. In recent years, solar energy-saving lamps have been widely promoted and used, and their lampshades, sockets, brackets, connecting rods, etc. All use Quality Alloy Aluminum Sheet profiles or pipes.

Advantages of thin aluminum sheets as lighting materials for lamps

1. Aluminum sheet can reduce the load of lamps. For example, a lamp post in an open-air sports field requires 80 spotlights. Lightweight aluminium lamps show their advantages.

2. The service life of outdoor lamps is required to be more than 10 years, and the aluminum alloy lampshade with good corrosion resistance can meet this requirement. Their surface is anodized, which not only improves hardness and wear resistance, but also allows for frequent scrubbing and a decorative finish.

3. In order to reduce weight and save energy, transportation vehicles also use aluminum wires, aluminum coils and aluminum electrical components. At present, aluminum alloys with good flexibility and creep resistance and effective low-voltage (12V) electrical contact materials have been developed.

4 x 8 aluminum sheets are the best-selling alloy aluminum sheets on the market, with alloys ranging from 1000 series to 8000 series. Therefore, the price of the national standard 4 x 8 aluminum sheet on the market must be of concern to everyone. Huawei Aluminum will analyze the market price of aluminum sheets for you.

1. Specifications and quality are fundamental

Specifications and quality affect the price of 4 x 8 aluminum plate is ultimately reflected in the specification and quality of the alloy. The aluminum plate market tends to be saturated. Under the competition, the price of 5052 aluminum plate is lower than that of 6061 aluminum plate and 6063 aluminum plate, while 6061 aluminum plate is a hot-selling product in the market, with strict process requirements, relatively few manufacturers, and the price is naturally more expensive. There are many 5052 Aluminum Sheet manufacturers, and the market is relatively saturated, so the price of 5052 aluminum plate is relatively cheap.

2. 4x8 aluminum sheet manufacturer is the key

At present, there are many 8x4 aluminum plate manufacturers in China, and there are hundreds of aluminum plate manufacturers in China alone. Among these manufacturers, the scale, nature and strength of the manufacturers are different, and the quotations for aluminum sheets are naturally different. It is recommended that consumers buy products from large, direct-selling, and powerful manufacturers, because these manufacturers have advanced equipment, high technology, better quality, and more reasonable prices.

3. Direct cost factors

The level of cost will directly affect the price level of 48 aluminum sheets. In the production process, it is inevitable to spend a certain amount of investment in manpower, material resources and technology. The higher the cost of 4x8 aluminum plate manufacturers in this regard, the higher the price.

Hot-rolled sheet, also known as hot-rolled sheet or hot-rolled steel plate, refers to an aluminum sheet product processed by a hot rolling mill. Usually, hot-rolled aluminum sheets are made from 4 x 8 aluminum sheet with a thickness of 400-500 mm that are processed multiple times by a hot-rolling mill. Due to the higher pressure during processing, the internal structure is more uniform and the grain size is better. The microstructure of the hot-rolled aluminum sheet is more uniform and dense. After anodizing, the surface texture of the hot-rolled aluminum plate is consistent, without ripples and color difference.

In the process of hot-rolled sheet processing, it is necessary to reasonably control the metallographic structure, mechanical properties, surface quality and geometric size and shape of the hot-rolled aluminum sheet to meet the quality requirements of subsequent processing and final products. In the hot rolling process of aluminum and aluminum alloys, the change of microstructure is a very complicated process. First, the grains of the material are deformed under the action of the strong rolling force, the as-cast grains are flattened, and the grains of the material are flattened along the rolling direction, while being elongated and strain hardened, and then dynamic recovery and dynamic regeneration may occur. crystallization.

Hot-rolled sheet products are generally divided into two categories, one is hot-rolled thick aluminum plate, and the other is hot-rolled aluminum coil. Hot-rolled thick aluminum plate refers to an aluminum alloy plate with a thickness of not less than 6.0 mm. The main varieties are hot-rolled plate (H112), annealed plate (O), quenched or quenched pre-stretched plate, etc. Hot rolled 1/8 aluminum sheet are usually used in hot rolling mills. It is produced by the block method, and its typical process is: ingot (homogenization) milling, edge rolling, heating, hot rolling, shearing, interruption, straightening.

Aluminum alloy sheet 5083 is a typical product of 5000 series anti-rust and anti-corrosion aluminum-magnesium alloy. In hull materials such as spe edboats, 5083 Aluminum Plate has sufficient strength and rigidity, and at the same time can reduce weight, resist seawater corrosion, and have good weldability. For example, large anti-submarine wing research ships and PTF-class speedboats are all 5000 series aluminum-magnesium alloy structures. In 1976, the all-welded aluminum structure of the US Navy also used 5083 aluminum plate and 5456 aluminum alloy as the main material. Since then, the British and French navies have separately built aluminum hulled catamarans. Aluminum alloy hulls have also become popular in Norway, Sweden, Japan and other countries.

Aluminum alloy plate 5083 is mainly used in the marine industry for shipbuilding and shipbuilding. 5083 aluminum plate is generally tempered by H116/H321/H112, and the length and width are 2 meters x 6 meters. Aluminum plate 5083 alloy has high toughness, corrosion resistance and weldability, which provides a good choice for building ships with strict weight requirements. Huawei Aluminum is one of the leading 8x4 Aluminium Sheet manufacturers in China, 5083 aluminum sheet is also our company's key product, we have rich experience in manufacturing and exporting 5083 aluminum alloy sheet, and we enjoy a high reputation among global customers.

From 1000 series and 3000 series aluminum plates commonly used by 4x8 aluminum sheet suppliers, to 6061 alloy aluminum plates for die stamping, etc. , they are widely used. But the aluminum alloy plate generally refers to, such as 6061 alloy aluminum plate, 5052 alloy aluminum plate, 5083 alloy aluminum plate, 3003 aluminum plate and so on. , is actually an aluminum alloy plate. In fact, by carefully analyzing the alloy composition of the aluminum alloy sheet, we must not be difficult to find a very important point, that is, they are all alloys of aluminum itself. Add various total amounts to the difference in alloy composition to achieve the purpose of strengthening, or to change some of its own differences.

The advantage of trailer skin aluminum is light weight but high strength. That is to say, under the same strength, the weight of the aluminum trailer is small. In other words, an aluminum trailer is stronger for the same weight. In aluminum alloy trailers, the structural requirements are particularly important. For example, in some places that need to bear relatively large forces, extruded profiles must be used to bear the weight. The use of aluminum sheet to manufacture trailer skin has huge economic and social benefits, and it is also the main reason for reducing the use of lightweight aluminum. Trailer aluminum plate application: 5000 series alloy: 5182 aluminum plate, 5083 aluminum plate, 5086 aluminum plate, 5052 aluminum sheet, 5454 aluminum plate, 5754 aluminum plate, 6000 series alloy: 6061 aluminum plate, 6063 aluminum plate, 6082 aluminum plate.

The side and inner panels of the trailer skin are 5052 alloy aluminum sheets with a thickness of 4-5 mm. The trailer body consists of aluminum alloy sheets and extruded aluminum profiles. The aluminum profile is used as a column, which is thicker in the middle and has a flange. The thickness of the flange is equal to the thickness of the aluminum alloy plate, the butt joint of the aluminum alloy plate is located at the reinforcing rib, and the upper and lower sides of the aluminum alloy plate are supported on the flanges of the upper and lower beams of the aluminum profile. In addition, 2.5mm, 3mm, 4mm and 5mm anti-skid aluminum pedals are usually used for trailer floors, and the application of anti-skid aluminum gratings in automobiles is also increasing year by year. The use of trailer aluminum plates can reduce the overall quality of the trailer to a certain extent, and realize the lightweight of the trailer body, thereby reducing carbon dioxide emissions, improving fuel efficiency, and ensuring energy saving to a greater extent.

Trailer skin aluminum has better toughness and better resilience. Lighter weight can be used to load cargo, creating more profit. This is also the biggest selling point of aluminum alloy trailers. Under normal load conditions, the aluminum alloy can fully meet the use requirements. Aluminum alloy plate has good oxidation resistance, corrosion resistance and excellent rust resistance. The finished 4 x 8 aluminum sheet for the trailer housing can last a long time. Aluminum alloy is easy to recycle and more environmentally friendly.
