Magnesium AZ31B
AZ31B
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).Applications
Diverse uses including aircraft fuselage, concrete tools, cellphone/camera/notebook computer cases, speaker cones and textile machinery can all benefit from light weight AZ31B.AZ31B is non-magnetic and has high electrical and thermal conductivity filling the requirements for RFI and EMI shielding in the electronics and computer industries.
Weldability:
Excellent weldability with gasshielded arc using AZ61A (preferred) or AZ92A filler rod; post weld stress relief is required to prevent stress corrosion cracking. Resistance welding is excellent.Specifications:
