What are the use of magnesium alloys in the automotive field?
In the past two decades, the world car production has continued to grow, with an average annual growth rate of 2.5%. The degree of automotive industrial development is one of the important signs of country development, and metal materials are an important basis for the development of automotive industrial. For energy saving and environmental requirements, automotive design experts want to try to reduce the weight of the car to achieve double effects of gasoline consumption and exhaust emissions. As the lightest structural material, the magnesium alloy can meet the requirements of increasingly stringent energy-saving exhaust emissions; a new car with light weight, less fuel consumption and environmentally friendly.
The benefits of magnesium alloy automotive parts can be simply summarized: small density, reducing the weight of the vehicle, indirectly reduces fuel consumption; the ratio of magnesium is higher than aluminum alloy and steel, which is close to aluminum alloy and steel than the stiffness, and can withstand certain loads. Magnesium has good castability and dimensional stability, easy to process, low waste rate; magnesium has a good damping coefficient, which is greater than aluminum alloy and cast iron, for the housing to reduce noise, for seat, rim Vibration can be reduced, improve the safety and comfort of the car.
Applications of magnesium allocation castings in automobiles have shown long-term growth trend. In the past decade, its annual growth rate exceeded 15%. In Europe, there have been 300 different magnesium components for assembly vehicles, and 2.5kg of magnesium is used in average of each European production. Optimistic estimates believe that due to weight loss, the demand for each car to magnesium will increase to 70-120kg. Currently, automotive instruments, seat racks, direction operation
The application of magnesium alloy die casting products in longitudinal system components, hosses, gearboxes, intake manifolds, hubs, engines, and security components.
