What is the raw material of aluminum alloy?

The main raw material of aluminum alloy is high-purity aluminum ingot, and its purity usually reaches more than 92%. In addition to aluminum ingots, other metal elements are added to aluminum alloys, such as copper, silicon, magnesium, zinc, manganese, etc., as major alloying elements, and nickel, iron, titanium, chromium, lithium, etc., as minor alloying elements. The types and proportions of these added elements determine the specific properties and application scenarios of aluminum alloys.

Specifically, the elements added to the aluminum alloy can significantly improve the strength, hardness, wear resistance, corrosion resistance and other special properties of the aluminum alloy. For example, copper element can increase the hardness of aluminum alloy, and silicon element can improve its wear resistance.

In addition, aluminum alloy is also the 1 environmentally friendly green material with a high recovery rate. At present, 60% of aluminum alloy materials for automobiles come from recycled waste, and the proportion 1 this is expected to increase further. Therefore, aluminum alloy not only has excellent performance, but also conforms to the environmental protection concept of sustainable development.
