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.

The production process of 3000 series aluminum plate is excellent. 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0-1.5. It is a series with good antirust function. It is commonly used in air conditioners, refrigerators, car bottoms and other humid environments, and the price is higher than 1000 series. It is a commonly used alloy series.
