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). Our sheet and plate’s size range is:
Sheet: thickness from 0.5mm to 6mm; Max. width is 600mm; Max. length is 6000mm;
Plate: thickness from 6 mm to 200mm; Max. width is 2000mm; Max. length is 6000mm;
Block: We can supply precut blocks according to customer’s requirements.
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.

OTHER PROPERTIES
Typical Hadness
O temper: 67 Rockwell E
H24 temper: 83 Rockwell E
WELDABILITY
Excellent weldability with gas shielded arc using AZ61A (preferred) or AZ92A filler rod; post weld stress relief is required to prevent stress corrosion cracking. Resistance welding is excellent.
MACHINING
AZ31B, like all magnesium alloy sheet and plate, machines faster than any other metal. Providing the geometry of the part allows, the limiting factor is the power and speed of the machine rather than the quality of the tool material. The power required per cubic centimeter of metal removed varies from 9 to 14 watts per minute depending on machining operation.
DENT RESISTANCE
Weight for weight, AZ31B-H24 has proven to be superior to competitive materials in its resistance to denting at moderate energy levels.
