As the lightest metal structure materials, magnesium alloys have high-quality strength and rigidity, good damping performance
AZ31B is a wrought magnesium base alloy with good room-temperature strength and ductility combined with corrosion resistance and weldability. Increased strength is obtained by strain hardening with a subsequent partial anneal (H24 and H26 tempers).
The demand for
magnesium and magnesium alloy has kept increasing since the 21 century. As reported,
the demand for magnesium alloys in western countries is increasing by 5%
annually. And magnesium alloy which has become the third largest metal that humans
use in a large scale is the most promising green metal
