The 2000 series alloy is a copper-added aluminum alloy, which is characterized by high strength, heat treatment and anodizing, but the disadvantages are poor welding
performance and corrosion resistance. Its strength grade is about 500Mpa. The products are mainly used in aviation parts, mechanical parts, structural parts, etc.
Commonly used 2000 series alloys are: 2014 2017 2024 2030 2618
