AZ31B Sheet, Plate, Block and coil
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).
SIZE RANGE:
Sheet: Thickness from 1mm to 6mm; Max. Width is 600mm; Max. Length is 6000mm;
Plate: Thickness from 6 mm to 200mm; Max. Width is 2500mm; Max. Length is 6000mm;
Block: We can supply cut-to-size blocks according to customer's requirements.
Coil: Thickness from 0.5 to 2.7mm, max. Width 240mm;
APPLICATIONS
Sheet and plate in AZ31B find application in medium strength service at temperatures below 150° C. Diverse uses including aerospace, aircraft, concrete tools, 3C (cell phone / camera / computer), 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.
Superplastic forming of AZ31B sheet at elevated temperatures allows production of a wide variety of intricate parts for automotive uses. Monocoque construction utilizing formed sheet can be adapted to many commercial applications.
