A notable feature of 5182 aluminum alloy plate is that it contains a large amount of magnesium. The magnesium content of the alloy gives it excellent corrosion resistance and weldability.
5182 rust-proof aluminum, zinc-aluminum alloy, 5182 aluminum plate is Al-Mg rust-proof aluminum, and its main component Mg content is as high as 4%~5%, so 5182 aluminum plate has strong corrosion resistance. In addition, a small amount of Si element is added to improve its weldability, which can adapt to welding methods such as gas welding, argon arc welding, and spot welding.
The performance of 5182 aluminum plate is similar to that of 5A02, but because the magnesium content is slightly higher than 5A02, and a small amount of silicon is added, the weldability is better than 5A02. The welding performance of 5182 aluminum plate with gas welding, argon arc welding, spot welding and roll welding is very good, and there is no big difference between the other properties.
