Xi'an Yuechen Metal Products. Co., Ltd. (XYMCO) has started to
produce the forged magnesium alloy plate, forged magnesium alloy
slab, forged magnesium alloy cube, forged magnesium alloy disc,
forged magnesium alloy block and forged magnesium alloy billet from
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).
AZ80A is the strongest of the AZ alloy family, offering good
strength at ambient or medium temperatures up to 120˚C (250˚f). It
has good corrosion resistance and can be forged for good
properties. Recent improvements on microstructure and cleanliness
makes our AZ80 ideal for high-performance forging applications.
ZK60A is the typical legacy magnesium forging alloy. Current and
historic uses are in military rotor and aircraft while the largest
volume application is forged magnesium wheels for motorsport. This
high strength alloy has good corrosion resistance but requires a
coating for all applications.

The sheet and plate shall conform to the tensile requirements in
above Table unless other agreement is made between seller and
purchaser. Mechanical Properties for sizes and tempers not shown in

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.
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.
Weight for weight, AZ31B-H24 has proven to be superior to
competitive materials in its resistance to denting at moderate
