Forged magnesium alloy plate slab cube disc block billet
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 2004.
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 above Table shall be as agreed upon by seller and purchaser.
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.
