Nonferrous metal materials for automotive parts

Recommended Posts

[Feilong Jiangli Edition]

Other metals except ferrous metals are collectively referred to as nonferrous metals. Aluminum, copper and its alloys are commonly used in automobile production.

Pure aluminium: Pure aluminium is a light metal material with a melting point of 660 C and a density of 1/3 of iron. Its conductivity and thermal conductivity are second only to silver and copper. It has good oxidation resistance and atmospheric corrosion resistance. Pure aluminum has very low strength and hardness, but its plasticity is very high. It can not be used as structural parts.

Aluminum alloy: Aluminum alloy is an alloy obtained by adding proper amount of tin, copper, magnesium, manganese and other elements into aluminum. After treatment, the mechanical properties of aluminum alloy are greatly improved. Aluminum alloy has high specific strength, good corrosion resistance, machinability and foundry, flexible strength design and beautiful surface can be achieved. It is obtained on automobiles. To a wide range of applications. For example, casting aluminum alloy is used to make cylinder block, cylinder head, rim and bumper, aluminum alloy is used to make radiator, condenser and other parts; aluminum and aluminum alloy are widely used in automobiles, on the one hand, the performance of these parts is improved, on the other hand, the lightweight of automobiles is achieved, which is an important development of Automotive materials in the future. The direction of the exhibition.
