Mg – Li alloy
XIAN YUECHEN METAL PRODUCTS CO., LTD. (XYMCO) is under R&D the
lightest structure Magnesium Lithium alloy materials and we believe
that it will be widely used for many fields like 3C, speaker,
extremely light weight (Density: 1.14-1.57g/cm3) and moderate
ultimate tensile strengths 14, 500 to 36, 000 lb/in2 (100 to 248
MPa). One such alloy, LA141A, has a density of only 0.045 lb/in3
(1245 kg/m3), or three-quarters that of magnesium high ductibility (43%), good
cold processing at room temperature, suitable for stamping, forging
and extrusion
Ultra light Magnesium Lithium (MgLi) alloy Materials
MgLi alloy is the most light weight metal structure materials,
density is generally 1.35-1.65g/cm3, has a high specific strength
and specific stiffness and excellent damping performance and
resistance to high-energy particle penetration. We also believed
that the MgLi alloys will be widely used for aerospace, aviation,
weapon, defense, nuclear industry and other potential industry
sectors.
After years of researching and developing hard works, XIAN YUECHEN
METAL PRODUCTS CO., LTD. (XYMCO) is becoming one of a leading
manufacturer and supplier of Magnesium Lithium (MgLi) alloy and
Aluminium Lithium Magnesium (AlLiMg) alloys with the material
grades for Mg14LiAl, Mg9LiAl, Mg9LiZn, Mg9Li3Al3Zn, Mg8LiAl,
Mg8LiAlY and Mg8Li3AlY.
XIAN YUECHEN METAL PRODUCTS CO., LTD. (XYMCO) can mass produce
LZ91,LA91, LA141, MA18 and MA21 magnesium lithium alloys in the
form of rectangular or round shape ingot by vacuum melting
techniques, and mass produce MgLi wrought alloys and its products
of magnesium lithium alloy slab, magnesium lithium alloy bock,
magnesium lithium alloy plate, magnesium lithium alloy sheet,
magnesium lithium alloy foil, magnesium lithium alloy strip,
magnesium lithium alloy coil, magnesium lithium alloy billet,
magnesium lithium alloy rod, magnesium lithium alloy bar, magnesium
lithium alloy tube, magnesium lithium alloy pipe, magnesium lithium
alloy wire, magnesium lithium alloy profile by casting, forging,
extrusion and hot rolling process. XYMCO also produces the
customized sizes (non standard sizes) magnesium lithium alloy
materials and its products according to customers’ requirements.
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.
Applications of ultra light Magnesium Lithium (MgLi) alloy
Aerospace: Dashboard, levers, skin, seat frames, aircraft down
side, fuel tank, and anti-cosmic dust shield wall, gyro mount
plate, etc;
Military field: Missile fin and shell, rocket head case, the
conversion device holder, aiming devices, stretchers, cartridges,
etc;
Transportation: Wheels, steering wheel locking device covers, small
toolbox door, pedal bracket, door frames, tail plate, motor cover,
front cover, air compressor cover, pumping tubing, cars, etc;
3C products: Laptop case, cell phone case, camera case, PDA / GPS
shell, high-end audio vibration film / tone pots, ultra-precise
frequency electronic lithium-magnesium alloy plate, conduit, etc.
