As the largest country with magnesium reserves, China's deep processing technology for magnesium alloys is currently becoming mature. With the development of the new energy vehicle market, China's magnesium alloy industry has the following advantages:
Rich - China has the world's largest magnesium reserves and production, with the eighth highest abundance of magnesium on Earth. Academician Pan Fusheng stated that magnesium resources are inexhaustible and inexhaustible;
Light - density is 2/3 of aluminum alloy and 1/4 of steel;
Strong - Good mechanical properties, high specific strength and rigidity;
Normal market prices range from 15000 to 20000 yuan/ton, which can compete head-on with steel and aluminum;
Green - has a low melting point, low melting energy consumption, and is easy to recycle. Especially in China, there is a complete and fast system for recycling magnesium alloy waste, and most forms of magnesium based substances are beneficial to the environment and human health;
Cool - High resistance to electromagnetic interference, impact and vibration absorption, good heat dissipation performance, good vibration reduction and noise reduction, can be absorbed by the human body, has excellent hydrogen storage capacity, and can be used as energy.
From this perspective, should the lightweight materials for automobiles be non magnesium alloys? At present, in China, the main focus is on the steering wheel frame and instrument panel frame. The average consumption of magnesium alloy for domestic models is only 2kg/vehicle, while in many best-selling models in Europe and America, the consumption of magnesium has reached 30kg/vehicle. This indicates that magnesium alloys have broad market prospects.
