Magnesium alloy is an alloy based on magnesium with the addition of other elements. It is characterized by low density (about ./magnesium alloy), high specific strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and good resistance to organic matter and alkali corrosion. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. Currently the most widely used is magnesium-aluminum alloy, followed by magnesium-manganese alloy and magnesium-zinc-zirconium alloy. Mainly used in aviation, aerospace, transportation, chemical industry and other industrial sectors. It is the lightest metal among practical metals. The specific gravity of magnesium is approximately that of aluminum and that of iron. It is the lightest metal among practical metals, with high strength and high rigidity.
Features
Its processing process, corrosion and mechanical properties have many characteristics: fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance and It is easy to recycle and has high thermal and electrical conductivity, non-magnetic, good shielding and non-toxic characteristics.
Application Scope Magnesium alloys are widely used in portable equipment and the automotive industry to achieve lightweight purposes.
At present, the application parts of magnesium alloy in automobiles can be summarized into categories.
Shell class. Such as clutch housing, valve cover, instrument panel, transmission body, crankcase, engine front cover, cylinder head, air conditioner casing, etc.
Brackets. Such as steering wheels, steering brackets, brake brackets, seat frames, mirror brackets, distribution brackets, etc.
According to relevant research, % of the fuel used by a car is consumed by the car's own weight. Every % reduction in the car's own weight, its fuel efficiency can be improved by more than %. Every time the car's dead weight is reduced, the fuel consumption per 100 kilometers can be reduced by about . Reduce emissions. Annual emissions are reduced by more than %. Therefore, reducing the weight of cars has a great impact on the environment and energy. Lightweighting of cars has become an inevitable trend. The size of the LCD screens on mobile phones and laptops is increasing year by year. In their support frames and back casings, Magnesium alloy is used. 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 to effectively dissipate internal heat to the outside.
Magnesium alloys are used in the casings and heat dissipation parts of computers and projectors that generate high temperatures inside. The use of magnesium alloy on the casing of the TV allows for no heat dissipation holes. Electromagnetic wave shielding properties The electromagnetic wave shielding performance of magnesium alloy is better than that of electroplating a shielding film on plastic. Therefore, the use of magnesium alloy can save the electroplating process of electromagnetic wave shielding film. Magnesium alloys are used in parts near vibration sources such as hard disk drive readout devices. If magnesium alloy is used on the fan blades, the vibration can be reduced and low noise can be achieved. In addition, magnesium alloy is used in the steering wheel and seats in order to improve impact absorption and reduce weight after the car is hit.
