Application of aluminum alloy in automobile lightweight
1. Corrosion resistant
Aluminum has a good corrosion resistance, its surface naturally formed oxide film has good corrosion resistance, so the "all-aluminum body" in the use of durability will be better than the traditional steel body.
2.Reducing the body weight and energy saving effect is obvious
Aluminum has good mechanical properties. Its density is only 1/3 of that of iron and steel. It has good thermal conductivity and machining performance is 4.5 times higher than that of iron. Aluminum alloy can reduce the weight of the vehicle by 10%. The fuel consumption of 100km can be reduced by 0.4l per 100kg, carbon dioxide emission can be reduced by 1kg, and fuel efficiency can be increased by 6%-8%.
3. Improve comfort and safety
Aluminum alloy car is in the case of not reducing the car capacity to reduce the weight of the car, the body center of gravity is reduced, the car is more stable and comfortable. Due to the good energy absorption of aluminum, it has an obvious advantage in the aspect of collision safety. The deformation area of the front of the car will produce folds in the collision, which can absorb a lot of impact force, thus protecting the driver and passenger behind.
4.Aluminum is easy to recycle
In the recycling process of aluminum -- aluminum products -- use -- recycling -- recycled aluminum ingots -- reprocessing into aluminum, the loss of aluminum is only about 5%, and its regeneration performance is higher than that of any common metal.
