Product Description

Magnesium Lithium Alloy LAZ931

Product introduction:
LAZ931 has good comprehensive mechanical properties, good strength and shape matching, and is suitable for the shell parts of aerospace, electronic 3C products with medium strength requirements. It is a typical commercial magnesium-lithium alloy with low density, medium strength, good shaping and good corrosion resistance. The density is equivalent to plastic, rigidity and toughness are much higher than plastics, and it has excellent shock absorption, damping and plasticity. It can be applied to sound film foil and is one of the most effective materials for weight reduction in aerospace metal materials. It can be applied to secondary load-bearing parts and various boxes and shells, such as electronic chassis shells, optical instrument structural parts, skins, dashboards, satellite rivets, honeycomb panels, heat pipes, notebook shells, mobile phone shells, sighting devices and the shell, etc.

 Magnesium-lithium alloy features:
1. Ultralight: The lightest metal structure material in the world, with a density of 1.35-1.65g/cm3, which is 1/2 lighter than aluminum alloy and 1/3 lighter than magnesium alloy.
2. Excellent rigidity: The rigidity is 22 times that of steel; the weight of magnesium and lithium required for the same rigidity is only 1/3 of that of steel.
3. Superplasticity: The tensile elongation rate of magnesium-lithium at high temperature can reach 758%. The superplastic forming process can obtain thin-walled parts with precise size, complex shape and uniform grain structure.
4. Good electrical and thermal conductivity: The thermal conductivity is about 300 to 400 times that of plastics, which is 30-50 times that of carbon fiber composite materials, and the electrical conductivity is about 1016 times that of plastics and 104 times that of carbon fiber composite materials.
5. Excellent shock absorption performance: With a large internal friction coefficient, energy can be consumed inside the metal, which can effectively improve the stability of the equipment, and is suitable for making equipment with shock absorption requirements, such as aerospace shock absorption parts, tank.
6. Excellent electromagnetic shielding performance: Magnesium lithium alloy has a good shielding effect on electromagnetic waves of different bands. It is suitable for making gyroscope shells, shielding shelters, anti-interference control cabinets, etc., to improve the safety of equipment, accuracy.
7. Good welding performance: Magnesium lithium is easy to weld with the body alloy and other magnesium alloys. Laser welding, friction stir welding, TIG welding, electron beam welding and brazing can be used for welding.
8. Excellent machining performance and cold forming ability: Magnesium-lithium machining performance is excellent, the surface quality is good, the cutting force is small, and the energy consumption is low. The cold working performance is very excellent, the total cold rolling processing rate can reach 90%, and it can be stamped and formed at room temperature.


Application area:
  1. Aerospace industry: Magnesium alloy materials can greatly reduce the weight and fuel cost of aircraft by virtue of their light weight. The reduction of aircraft weight can improve aircraft maneuverability and combat effectiveness. The excellent shock absorption performance of magnesium-lithium alloy can reduce the problems of engine operation and aerodynamic noise caused by missiles, carrier rockets and aircraft in flight.
  2. Military field: Magnesium alloy is used as a lightweight structural material, and magnesium-lithium alloy is used to replace aluminum alloy and titanium alloy, which can achieve a weight reduction effect of 20% to 40%.
  3. 3C field: Magnesium-lithium alloy has good cold working performance, can realize room temperature stamping forming, and is widely used in electronic products such as computers and communication equipment. In addition, magnesium-lithium alloy also has excellent electromagnetic shielding performance. The use of magnesium-lithium alloy to prepare notebook LCD screen frames, back shells, keyboard frame shells and other parts can reduce weight, enhance heat dissipation, and increase impact resistance. Electromagnetic interference makes the transmitted data more real and accurate.
