The benefits of magnesium alloy automobile parts can be simply summarized as: low density, can reduce vehicle weight, indirectly reduce fuel consumption; magnesium strength was higher than Aluminum Alloy and steel, stiffness ratio close to Aluminum Alloy and steel, can withstand a certain load; magnesium has good casting properties and dimensional stability, easy processing, low reject rate magnesium; high damping coefficient, damping is larger than Aluminum Alloy and cast iron for shell can reduce the noise for a seat, wheels can reduce vibration and improve vehicle safety and comfort. As early as 1930, magnesium alloys were used on the pistons in a racing car and on the gasoline pump in opel. The last century in 60s some car consumption reached 23 kg, mainly used as a valve shell, air cleaning box, brake and clutch pedal, etc.; on the century at the beginning of 80s, strict control of iron, copper, nickel and other impurities, the corrosion resistance of magnesium alloy has been solved, at the same time, but also greatly promoted the application of cost reduction magnesium alloy in the automobile. Starting in the 90s of the last century, Europe, America, Japan and Korea began to use magnesium alloys for automobile parts. The application of magnesium alloy die castings in automobiles has shown a long-term growth trend. Over the past ten years, its annual growth rate has exceeded 15%. In Europe, 300 different magnesium components have been used to assemble cars, with an average of 2.5kg mg per European car. Demand for magnesium for each car will rise to 70 - 120kg. At present, the application of Mg alloy die casting products on automotive instruments, seats, steering systems, engines, transmissions, intake manifolds, hubs, engines and safety components.
