5A03 Aircraft Aerospace Grade Aluminum Plate Sheet

5A03 is Al-Mg rust-proof aluminum. The performance of the alloy is similar to that of 5A02, but because the magnesium content is slightly higher than that of 5A02 and a small amount of silicon is added, its weldability is better than 5A02. The alloy is welded by gas welding, argon arc welding. The welding performance of welding and seam welding is very good, and there is no big difference between the other properties. Because 5A03 aircraft aerospace grade aluminum plate sheet has high strength, easy processing, easy coloring, good corrosion resistance, strength is not affected by temperature and humidity, light weight, long service life and other characteristics, the aluminum sound barrier mainly uses 5A03 alloy.
