The 4000 series aluminum plates belong to the series with high silicon content. Generally, the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials and welding materials; Low melting point, good corrosion resistance Product description: It has the characteristics of heat resistance and wear resistance.

Aluminum coils are widely used in electronics, packaging, construction, machinery, etc. There are many aluminum coil manufacturers in China, and the production process has caught up with that of developed countries. According to the different metal elements contained in aluminum coils, aluminum coils can be roughly divided into nine categories.
