Magnesium alloy applications in the automotive industry, the benefits of magnesium alloy automotive parts can be summarized as: low density, can reduce the weight of the vehicle, indirectly reduce fuel consumption; magnesium than aluminum alloy and steel, the stiffness is close to the aluminum alloy and Steel, can withstand a certain load; Magnesium has good castability and dimensional stability, easy processing, low reject rate; Magnesium has a high damping coefficient, vibration damping is greater than aluminum alloy and cast iron, used in the shell can reduce noise, with In the seat, rims can reduce vibration, improve the safety and comfort of the car. As early as 1930, magnesium alloys were used on the pistons of a racing car and the oil pump boxes on Opel cars. In the 1960s, the amount of 23 kg used in some vehicles was mainly used for valve housings, air cleaning tanks, brakes, clutches, and pedal racks; in the early 1980s, strict controls were imposed on the contents of impurities such as iron, copper, and nickel. The corrosion resistance of magnesium alloys has been solved. At the same time, the cost reduction has greatly promoted the application of magnesium alloys in automobiles. Since the 1990s, Europe, the United States, Japan, and South Korea have begun to use magnesium alloys for automotive parts. The application of magnesium alloy die castings in automobiles has shown long-term growth. In the past ten years, its annual growth rate has exceeded 15%. In Europe, there are already 300 different magnesium parts used to assemble cars. On average, each car produced in Europe uses 2.5 kg of magnesium. The demand for magnesium in each car will increase to 70-120 kg. At present, magnesium alloy die-casting products are used in automotive instrumentation, seat frames, steering system components, engine covers, transmissions, intake manifolds, hubs, engines, and safety components.
Chongqing Chang'an Group Co., Ltd.: Completed trial production of magnesium alloy instead of aluminum alloy for the upper and lower shells of the JL462Q engine transmission. It has become an annual production capacity of 1500t automobile transmission die casting. At the end of 2003, seven components such as the upper and lower parts of the transmission, the box body extension and the cylinder cover had been loaded into vehicles in batches, and passed the small-batch loading test, which is currently undergoing the final batch loading assessment before mass production; in addition, The company also plans to use magnesium alloys to replace more parts, such as the steering wheel, seat frame, etc., and gradually increase the usage of each vehicle to 20Kg. FAW Group: Successful pilot production of magnesium alloy die castings such as valve housing covers, gearbox covers, and engine oil sprays, in which the valve chamber cover has passed the loading test. Dongfeng Motor Co., Ltd.: Focused on the industrial application of the magnesium alloy transmission top cover, completed 100,000 standard bench tests and successfully passed the assessment; at the same time, the vacuum separator of the loaded vacuum booster was installed on the center. A survey of the application status of the pedal step shows that the application effect is good.
