Magnesium-Lithium Alloy: A Tool for Lightening and Thinning Laptops
At present, the commonly used shell materials for light and thin notebooks are aluminum alloy, magnesium aluminum alloy and carbon fiber composite materials.
In recent years, benefiting from the ultimate pursuit of light and thinness by major manufacturers and the efforts of colleagues in the material industry, magnesium-lithium alloys have gradually been applied to thin and light notebooks, and have made significant progress in lightweight and portability, gaining market share. 's approval.
Magnesium-lithium alloy is the lightest metal structural material in the world. The reason why it is favored by major manufacturers and consumers is that it combines the excellent properties of aluminum alloy, magnesium aluminum alloy and carbon fiber composite materials, and has outstanding comprehensive advantages. The main points are as follows:
01
Ultra-light, the density of magnesium itself is not high, only 1.74g/cm³. Because of the addition of lithium, its density drops to 1.3-1.6g/cm³, which is the lowest density structural metal material at present. It is 1/2 lighter than aluminum alloy and 1/3 lighter than magnesium alloy, which can better achieve weight reduction effect and meet consumers' ultimate pursuit of lightness and thinness.
02
Good electrical and thermal conductivity, thermal conductivity is about 300-400 times that of plastic, 30-50 times that of carbon fiber composite material, electrical conductivity is about 1016 times that of plastic, and 104 times that of carbon fiber composite material, which can achieve better heat dissipation It avoids the defect of poor heat dissipation of thin and light notebooks.
03
Excellent shock absorption performance, with a large internal friction coefficient, can consume energy inside the metal, which can effectively improve the stability of the product.
04
Excellent electromagnetic shielding performance, magnesium-lithium alloy has a good shielding effect on electromagnetic waves in different bands, improving the safety and accuracy of the equipment.
05
Excellent machinability and cold forming ability, excellent machinability, good surface quality, low cutting force and low energy consumption. Excellent cold working performance, capable of room temperature stamping and improving production efficiency.
06
Under the premise of having the above advantages, the cost is lower than that of carbon fiber composite materials, which helps manufacturers to control costs.
Thanks to the above advantages, magnesium-lithium alloys have been successfully applied in thin and light notebook shells at home and abroad and are favored by notebook material manufacturers.
The notebook uses a magnesium-lithium alloy casing and weighs about 990 grams.
Magnesium-lithium alloys have won the recognition of the market for their excellent performance. It is believed that with the addition of magnesium-lithium alloys, ultra-portable thin and light less than 1000 grams in the market will become the mainstream of the market in the future.
Our company has been focusing on the research and development and production of special and new light alloys for many years. Magnesium-lithium alloys, aluminum-lithium alloys, high-strength heat-resistant magnesium-rare earth alloys and ultra-high-strength heat-resistant aluminum-copper alloys, as well as high-performance aluminum alloy/magnesium alloy castings, forgings, rare rare earth alloys, high-purity alloys and other products independently developed and produced are widely used in National defense and military industry and 3C and other fields.

Magnesium alloy surface treatment technology
Because magnesium alloy is extremely active, there is often a layer of oxide on the surface, so the surface treatment of magnesium alloy is difficult. Special treatment methods must be adopted. The existing surface treatment technology is not mature, often making the alloy surface rough and using a large number of non -environmental chemicals. In recent years, the advanced surface treatment technology of magnesium alloy has developed new development.

Research on the application of magnesium alloy on high -speed guide rails of railway transportation
At present, in high -speed rail transit railways, light aluminum alloys are usually used for vehicle structures. However, in recent years, with the increase of railway speed and the importance of energy conservation, the demand for reducing weight has been further increased. The proportion of magnesium is more than 30%smaller than aluminum.
