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.

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.

SURFACE TREATMENT

treatment are readily applicable. AZ31B also responds well to
plasma electrolytic oxidation finishing.

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.

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
