3003 aluminium alloy - Aluminum Sheet Supplier
3003 aluminium alloy VS 3004. 3004 aluminum alloy has a higher content of magnesium than 3003 aluminum. The role of Mg has two sides. In addition to surface quality it also has a solid solution strengthening effect which can increase the strength of Al-Mg alloys by 10%. Therefore Al-Mg-Mn alloys (such as 3004 alloy) are widely used.
