What's Magnesium lithium (MgLi) alloys and Aluminium Lithium alloys
Magnesium lithium (MgLi) alloys are among the lightest structural
materials. Aluminium lithium alloys are a range of advanced
aluminium alloys. Their key advantage over standard aluminium
alloys is a lower density combined with improved elastic modulus.
Resistance to fatigue cracking is also generally superior to
standard 2000 and 7000 series aluminium alloys. Newer aluminium
lithium alloys have improved corrosion resistance and greater
toughness than their predecessors.

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
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.
AZ31B is non-magnetic and has high electrical and thermal
conductivity filling the requirements for RFI and EMI shielding in
the electronics and computer industries.
Superplastic forming of AZ31B sheet at elevated temperatures allows
production of a wide variety of intricate parts for automotive
uses. Monocoque construction utilizing formed sheet can be adapted
to many commercial 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.
O temper: 67 Rockwell E
H24 temper: 83 Rockwell E
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
