Austempered Ductile Iron (ADI) is a type of ductile cast iron that has been heat-treated to improve its strength, toughness, and wear resistance. It is produced by applying a special heat treatment process called austempering to ductile iron.

 

The process involves heating the iron to a high temperature to form austenite, then rapidly cooling it in a bath (usually salt) to a specific temperature range. It is then held at that temperature until the structure transforms into bainite, a tough and strong microstructure.

 

Compared to regular ductile iron, Austempered Ductile Iron offers:

 

Higher strength

 

Better wear resistance

 

Good ductility and impact toughness

 

Lower weight for the same performance (ideal for lightweight design)

 

ADI is widely used in industries such as automotive, agriculture, mining, and construction for components like gears, crankshafts, sprockets, and wear parts.

 

Aluminum foil is a common household and industrial product, valued for its flexibility, barrier properties, and conductivity. When considering its use in applications involving heat, such as cooking or certain industrial processes, understanding its melting point is crucial.

 

The Melting Point of Aluminum Foil is a well-defined physical property, which is approximately 660 degrees Celsius (660.3°C). This is equivalent to about 1220 degrees Fahrenheit (1220.5°F). At this temperature, the solid metal transitions into a liquid state.

 

Standard aluminum foil is typically made from aluminum that is very high in purity, often 99% or even higher (like alloy grades 1100, 1235, or 8011). While some minor alloying elements might be present to enhance specific properties like strength or formability, their concentrations in common foils are generally too low to significantly alter the melting point from that of pure aluminum.

 

This relatively high melting point is why aluminum foil can be safely used in conventional kitchen ovens, which typically operate at temperatures up to around 260-290°C (500-550°F). This is well below the temperature required to melt the foil, allowing it to be used for baking, roasting, and covering dishes without risk of melting.

 

It's important to distinguish the melting point from ignition or burning. When aluminum foil reaches 660°C, it will turn into liquid aluminum. It does not readily "burn" in air at this temperature in its sheet form, although oxidation will occur. For aluminum to combust, it usually needs to be in a very fine powdered form and exposed to much higher temperatures or a pure oxygen environment.

 

In summary, the melting point of aluminum foil is effectively that of pure aluminum, around 660°C (1220°F). This characteristic makes it suitable for a wide range of high-temperature applications, most notably in cooking, where typical appliance temperatures do not approach this threshold.

It is also the aluminum sheet with the earliest application time, the most mature production process, the widest application range and the most advantageous price among the 8 series aluminum sheets. So, what are the characteristics of the 1000 series pure aluminum sheet, and what are its common uses?

The representative grades of series 1000 aluminum sheet: 1050 aluminium sheet, 1060 aluminum sheet, 1100 aluminum sheet and 1200 aluminum sheet. Features of 1050 aluminum sheet are:

1, Low density.

The specific gravity of pure aluminum is 2.71. Under the same volume, the weight of series 1050 aluminum sheet is only 35% of iron.

2, It can be strengthened.

Series 1050 aluminum sheets can be cold-worked to increase their strength, up to more than 1 times.

3, Easy to process.

The 1000 series aluminum sheet has good plasticity and is very suitable for machining, such as sawing, shearing, milling, boring, planing, turning, etc.

4, Corrosion resistance.

The surface of the 1050 aluminium sheet without special processing will naturally form a dense protective film of aluminum oxide, which is difficult to be destroyed. Therefore, the 1000 series aluminum sheet is very resistant to atmospheric (including industrial atmosphere, marine atmosphere) corrosion and water corrosion ability.

5, No low temperature brittleness.

The strength and plasticity of the 1000 series aluminum sheet will not be reduced and reduced due to temperature. Below zero, the lower the temperature, the higher the strength and plasticity.
