Xian 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.
Dent Resistance of 1mm Gauge Sheet (Dent depth in mm from 25mm spherical redius indentor on 350mm span)

ZK60A
ZK60A is a wrought magnesium base alloy containing zinc and zirconium. Increased strength is obtained by artificial aging from the as-fabricated form. ZK60A-T5 has the best combination of strength and ductility at room-temperature of the wrought magnesium alloys.

APPLICATIONS
Forgings and extrusions in ZK60A find application in high strength parts for use primarily where the service temperature is below 150°C. ZK60A forgings can be used where pressure tightness or machinability are required. That parts are dimensionally stable during and after machining is also an important design consideration.
Forgings and extrusions in ZK60A find application in high strength parts for satellites, helicopter gearboxes and rotor hubs, bicycle frames, roadwheels, missle frames and interstage fairings, brake housings and landing gear struts.

SPECIFICATIONS

Dimension Scope
Forgings: Max. length 1000mm, max. width 500mm, max thickness 330mm.
Extrusions: Diameter 6mm - 180mm for round bar; thickness and width 10-220mm for square/rectangular section. Length: 100mm - 6000mm
Thickness and width are inter-dependant.

HEAT TREATMENT
As-fabricated (F) forgings can be converted to the precipitation treated temper (T5) by heating to 150°C for 24 hours, followed by air cooling.

WELDABILITY
ZK60A is not considered to be weldable by conventional techniques due to hot-shortness cracking. However, resistance welding response is excellent. Friction stir welding can be used to join ZK60A to itself and other magnesium alloys.

MACHINING
ZK60A, like all magnesium alloy forgings, 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 the operation.
