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.
