With the development of various technologies of hardware and software, its function, structure and application are also changing, and the market demand is also changing. In view of consumers' pursuit of product appearance and portability, lightweight notebook has become the object of layout of major notebook computer manufacturers, and lightweight and ultra portable have become the development trend of notebook computers.
Magnesium-lithium alloy is used to laptop
Notebook computer products are composed of various structural parts and components. In order to achieve lightweight, the choice of shell material is also the main way to reduce weight. At present, the common shell materials of the light and thin laptop are mainly aluminum alloy, magnesium aluminum alloy and carbon fiber composite.
Magnesium lithium alloy is the lightest metal structural material in the world. It is favored by major manufacturers and consumers because it has the excellent properties of aluminum alloy, magnesium aluminum alloy and carbon fiber composites. The main points are as follows:
- Ultra light. The density of magnesium itself is not high, only 1.74g/cm. Because the addition of lithium reduces its density to 1.3-1.6g/cm, it is the structural metal material with the lowest density at present. It is 1 / 2 lighter than aluminum alloy and 1 / 3 lighter than magnesium alloy, which can better realize the effect of weight reduction and meet the ultimate pursuit of lightness and thinness of consumers.
- It has good conductivity and thermal conductivity. Its thermal conductivity is about 300-400 times that of plastic, 30-50 times that of carbon fiber composite, 1016 times that of plastic and 104 times that of carbon fiber composite. It can achieve better heat dissipation effect and avoid the defect of poor heat dissipation.
- Excellent shock absorption performance and large internal friction coefficient, which can consume energy inside the metal and effectively improve the stability of the product.
- Excellent electromagnetic shielding performance. Magnesium lithium alloy has a good shielding effect on electromagnetic waves in different bands, so as to improve the safety and accuracy of the equipment.
- Excellent machining performance and cold forming ability, excellent machining performance, good machining surface quality, small cutting force and low energy consumption. Excellent cold working performance, capable of stamping at room temperature and improving production efficiency.
In addition to the above advantages, the cost of magnesium lithium alloy is lower than that of carbon fiber composites, which is helpful to cost control. Therefore, magnesium lithium alloy has been successfully applied in light and thin notebook shell at home and abroad, and is favored by notebook material manufacturers. Magnesium lithium alloy has won the recognition of the market for its excellent performance. The ultra portable and thin magnesium lithium alloy is gradually becoming the mainstream of the market
