Classification of Aluminum Alloy

1.Deformed aluminum alloys: Processing rate > 12%, including anti-rust aluminum (3XXX/5XXX series, containing Mn/Mg, non-heat-treatable strengthened), hard aluminum (2XXX series, containing Cu - Mg, capable of aging strengthening), super-hard aluminum (7XXX series, containing Zn - Mg - Cu, with the highest strength), and forged aluminum (6XXX series, containing Mg - Si, excellent thermal plasticity). 

2. Cast aluminum alloys: Such as the Al-Si series (ZL1XX, excellent casting properties, e.g. ZL102 contains 12% Si), the Al-Cu series (ZL2XX, good heat resistance and high strength), and the Al-Mg series (ZL3XX, strong corrosion resistance and shiny surface).
