The characteristics of magnesium alloy: in the practical metal is the lightest metal, the proportion of magnesium is about 2/3 of aluminum, is 1/4 of iron. It is the lightest metal in the practical metal, high strength, high rigidity.

Application: Magnesium alloy is widely used in portable equipment and automobile industry to achieve the purpose of lightweight. Although the proportion of magnesium alloy is heavier than that of plastic, its strength and elasticity per unit weight are higher than that of plastic. Therefore, in the case of parts with the same strength, magnesium alloy parts can be thinner and lighter than those of plastic.

In addition, because the specific strength of magnesium alloy is higher than that of aluminum alloy and iron, the weight of aluminum or iron parts can be reduced without reducing the strength of the parts. Applications: LCD screens on mobile phones and laptop computers grow in size every year, using magnesium alloy in their support frames and back cases.

Heat transfer: although the thermal conductivity of magnesium alloy is not as good as that of aluminum alloy, it is dozens of times higher than that of plastic. Therefore, magnesium alloy is used in electrical products, which can effectively spread the internal heat outside. Applications: use magnesium alloy in enclosures and heat dissipation components such as computers and projectors that generate high internal temperature. The use of magnesium alloy in the case of the TV can achieve no heat dissipation holes.

Electromagnetic wave shielding: the electromagnetic wave shielding function of magnesium alloy is better than that of electroplating shielding film on plastic. Therefore, the electroplating process of electromagnetic wave shielding film can be eliminated by using magnesium alloy. Application: Magnesium alloys are used in housing and shielding materials for mobile phones.

Mechanical processing function: magnesium alloy has less cutting resistance than other metals, and can be processed at a faster speed when machining. Table: cutting resistance of various metals (the cutting resistance of magnesium alloy is 1) Metal name cutting resistance Magnesium alloy 1.0 aluminum alloy 1.8 brass 2.3 cast iron 3.5 Good sag resistance: compared with other metals, magnesium alloy has a large deformation resistance, and the sag caused by conflict is less than other metals. The vibration? Impact absorption: magnesium alloy can be used in drive and transmission parts to reduce vibration because of its good absorption of vibration energy.

In addition, the impact energy absorption function is good, magnesium alloy has better elongation than aluminum alloy, after being impacted, can absorb the impact energy without fracture. Application: Use of magnesium alloys in parts around vibration sources such as readout devices for hard disk drives. If the magnesium alloy is used in the fan blade, the vibration can be reduced to a low tone. In addition, in order to improve the impact absorption and lightweight of the car after being hit, the steering wheel and the seat make
