The applications of magnesium alloy castings in automobile mainly include gearbox and shell cover, clutch shell and shell cover, pump body, steering wheel, cylinder head cover, automobile hub, instrument panel, automobile seat frame and protective bars. In the production and manufacturing process of some automobiles, magnesium alloy parts used in the whole vehicle reach 48 kg. Because magnesium alloy castings have good plasticity, formability, high corrosion resistance and high strength, they are very popular in the automobile industry. In order to improve the technical content and competitiveness of products, magnesium alloy parts are gradually used.
In addition to passenger vehicles, commercial trucks, motorcycles and bicycles can also use magnesium alloy castings in large quantities, which can bring benefit improvement or convenience to our life. In recent years, a large number of magnesium alloy castings and products have been used in rail transit, which can not only reduce the weight of the vehicle and reduce energy consumption, but also reduce noise and shock. It is a general trend that magnesium alloy honeycomb panels are widely used in inner walls and floors of high-speed trains and urban light rail trains.
In the field of aerospace, the advantages of magnesium alloys are not to mention. More than 6 tons of magnesium alloy castings were used in some heavy bombers. The industry estimates that a pound of weight loss in aerospace costs $300 for commercial aircraft, $3,000 for fighter jets and $30,000 for spacecraft. At present, it has become normal to use magnesium alloy in various industries.
