Description
Al-MG-based Non-heat-treated Alloy
It is the most representative aluminium alloy in Japan. It has excellent corrosion resistance, weldability, formability, and seawater resistance. Additionally, Kobe Steel's ALJADE® has achieved excellent flatness and thickness tolerance. Additionally, residual stress inside the plate is largely removed, making it extremely easy to work with.
Suitable fields:
- General Machine Parts
