What is the difference between alloy aluminum plate and pure aluminum plate
We all know aluminum alloys, and aluminum doors and windows are the most commonly seen in daily life. For the frequently mentioned alloy aluminum plate and pure aluminum plate, although the two belong to the same aluminum plate, what is the difference between the two and what is the connection?
1. Alloy composition
1. The hardness of the two is different. The hardness of the alloy aluminum plate is greater than that of the aluminum plate. The aluminum alloy plate is based on the aluminum plate with copper, silicon, magnesium, zinc, manganese and other alloy elements added, and the hardness will be greater than that of the aluminum plate.
2. The conductivity of the two is different. The conductivity of the alloy aluminum plate is better than that of the aluminum plate. In some power industries, alloy aluminum plates are their first choice.
3. The corrosion resistance of the two is different. The corrosion resistance of alloy aluminum plate is much better than that of aluminum plate. Therefore, in some corrosive industries, aluminum alloy plates are more popular than aluminum plates.
4. The plasticity of the two is different. The plasticity of the alloy aluminum plate is better than that of the aluminum plate, so the application range of the alloy aluminum plate is wider than that of the aluminum plate.
5. The stretching degree of the two is different. Aluminum alloy plate is easier to stretch than aluminum plate and has stronger ductility, so it has a wider range of applications.
6. The importance of the two is different. The alloy aluminum plate is heavier than the aluminum plate. This is because some heavy metals are added to the alloy aluminum plate, which has a greater mass than aluminum.
7. The weldability of the two is different. The weldability of the alloy aluminum plate is stronger than that of the aluminum plate. Alloy aluminum plates can be better used in some occasions where welding is required, which also limits the scope of application of aluminum plates.
2. Application field
Due to the different composition of the alloy, the characteristics of the aluminum plate and the aluminum alloy plate are different, and the application range is very different. The aluminum plate is mainly used for household appliances, mold manufacturing, ship plates, etc., and the aluminum alloy plate is mainly used for industrial profiles. It is widely used in aerospace, rail transit, electronic appliances.
