Introduction of Zggdmetal 7020 aluminum tube
7020 aluminum tube is a
high-strength aluminum-zinc-magnesium alloy, featuring
excellent weldability, fatigue resistance, and mechanical strength. It is widely used in
aerospace, railway structures, military components, and other engineering fields requiring
strong yet lightweight materials. It offers superior stress corrosion resistance and can be heat-treated to T5/T6 conditions for optimal performance.
Advantages of Zggdmetal 7020 aluminum tube pipe
- High strength, excellent load-bearing capacity
- Good weldability and heat-treatable
- Superior fatigue and crack resistance
- Resistant to stress corrosion
- ldeal for heavy-duty welded structures
