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.
