Why is 5052 widely used in automobiles

2023-08-11

5052 aluminum plate is an aluminum magnesium alloy, which is a commonly used aluminum alloy material and is very popular in the automotive industry. It is widely used in both passenger and commercial vehicles.
5052 aluminum plate is mainly used for automotive fuel tanks, engine outer panels, trunk panels for buses, anti slip decorative panels for buses, automotive heat shields, automotive brake baffles, etc.
5052 aluminum plate is widely used in automotive components, mainly due to the excellent characteristics of the material itself:
1. The density of aluminum alloy is relatively low, and the application of aluminum alloy can achieve vehicle lightweight, improve vehicle performance, and improve fuel economy.

2. Higher specific strength. In addition to magnesium, there are also a small amount of manganese, chromium, beryllium and other elements in the alloy of 5052 aluminum plate, which improves the resistance to stress corrosion cracking, reduces the tendency of welding cracks, maintains stability against severe impacts, and is less prone to cracks, ensuring the safety of the vehicle.
3. Corrosion resistance. Magnesium is the main alloying element in 5052 alloy aluminum plate and is a widely used rust resistant aluminum.
