Magnesium alloy in the application of automotive parts advantages

Magnesium alloy material is the lightest engineering structural material at present, the use of magnesium alloy to manufacture automobiles, especially new energy electric vehicle parts can achieve obvious energy-saving and emission reduction effects, now the industrial developed countries are as much as possible to use lightweight materials to manufacture auto parts. The application advantages of magnesium alloy materials in the development of parts are roughly the following four points:

1. The mass density of magnesium alloy material is small, and its application in the development of new energy vehicles can significantly reduce the mass;

2, magnesium alloy material has excellent shock absorption, can withstand greater impact and vibration, compared with aluminum, steel and other materials more outstanding performance, for maintaining the stability of the car operation;

3. Good specific strength and stiffness. Compared with steel and aluminum alloy, the specific stiffness and specific strength of magnesium alloy are higher under the same mass condition.

4, magnesium alloy material can be recycled. The extraction of magnesium alloy materials is mainly based on renewable resources, which can realize recycling. In addition, magnesium has a relatively low melting point and consumes relatively little energy to recycle.

Tesla cars are a class of new energy electric vehicles, and under the conditions of ensuring safety and riding comfort, its own quality is of course the lighter the better. In the case of equal charging, the lighter body can go further. At present, in addition to more improvements in design, making parts from lightweight materials as much as possible is the best measure to reduce the net weight of vehicles. Aluminum and magnesium are the most desirable lightweight materials, the density of aluminum is 2.70g/cm, while the density of magnesium is only 1.74g/cm, the weight reduction effect of magnesium is greater than that of aluminum, and magnesium and magnesium alloys have become one of the best materials for manufacturing Tesla electric vehicles.

The advantages of electric vehicles made of magnesium alloy can be summarized as follows: significantly reduce the net weight of vehicles, reduce power consumption, and reduce greenhouse gas emissions; Improve parts integration, reduce parts processing, manufacturing and assembly costs; The design flexibility is large, and the use of magnesium alloy with good formability can improve the shock resistance and collision resistance of the car. Improve the stiffness of the car; Increase the recovery rate of used parts; Improve vehicle safety and operability. For every 10% reduction in vehicle weight, about 5.6% of fuel is saved, which in turn reduces greenhouse gas emissions. Magnesium alloy is a superior material for the manufacture of automobile, motorcycle and other transportation equipment, which can not only reduce the net weight of the vehicle, reduce energy consumption, improve the acceleration and braking performance of the vehicle, but also significantly reduce the driving vibration and noise, and improve the driving and riding comfort. The application of magnesium alloy in automobiles is mainly die-casting parts and castings, especially die-casting parts, and more than 75% of the current die-casting parts are used in the automobile and motorcycle manufacturing industry.
