Aluminum alloy is a light metal material that uses aluminum as a matrix with small amounts of other alloying elements such as copper, magnesium and zinc. The aluminum alloy composition elements play a role in aluminum alloy to enhance its mechanical, physical and chemical properties of aluminium alloy. The main alloying elements of aluminum alloy include copper, silicon, magnesium, zinc, manganese, etc. These elements play different roles in aluminum alloys. For example, copper can improve the strength and corrosion resistance of aluminum alloys, silicon can improve the hardness and wear resistance of aluminum alloys, magnesium and zinc can improve the tensile strength and toughness of aluminum alloys, and manganese can improve the processing performance of aluminum alloys. In addition, aluminum alloys can have small amounts of other elements, such as iron, titanium and chromium, added to further adjust their properties. For example, iron can improve the thermal and electrical conductivity of aluminum alloys, titanium can enhance the corrosion resistance of aluminum alloys, and chromium can improve the polishing properties of aluminum alloys.

Common aluminum alloys can be classified according to their different alloying elements. Aluminum alloys can be divided into two categories: cast aluminum alloys and deformed aluminum alloys.

Casting aluminum alloy is mainly used for casting various parts and components, its alloy composition and processing technology is relatively simple. Common casting aluminum alloys are aluminum-silicon system, aluminum-copper system, aluminum-magnesium system and so on.

Deformation of aluminum alloys can be plastic processing, made into a variety of profiles and plates, used in the manufacture of a variety of aluminum products. The alloy composition and processing technology of deformed aluminum alloy are relatively complex, and can be selected according to different applications and performance requirements. Common deformed aluminum alloys include rust-proof aluminum alloy, hard aluminum alloy, super-hard aluminum alloy and so on. Super hard aluminum alloy, etc. These classified aluminum alloys have different alloy compositions and processing techniques to meet different application requirements.


In general, the aluminum alloy composition elements can be selected and adjusted according to the needs to achieve different mechanical properties, physical properties and chemical properties requirements.
