5A03 ALUMINUM SHEET

　　5A03 aluminum plate is an aluminum alloy of Al-Mg system. Because the magnesium content of 5A03 is slightly higher than 5754 aluminum alloy, the corrosion resistance and tensile strength of 5A03 are higher than 5754. The silicon content in 5A03 alloy is higher than 5754, so the welding performance is higher than 5754, which can be used for gas welding, argon arc welding, spot welding and roll welding. Since magnesium aluminum alloys such as 5A03 and 5754 have high strength, easy processing, easy coloring, good corrosion resistance, strength not affected by temperature and humidity, light weight, long service life, etc., so aluminum alloy sound barriers mainly use 5A03 and 5754 alloys.
