Aluminium alloys in lightweight of automobile has natural advantages

         First, weight loss and energy-saving . The mechanical properties of aluminum, its density is only 1/3 of iron and steel, has good thermal conductivity after copper, 4.5 times times higher mechanical properties than iron, and the naturally occurring oxide film on its surface has good corrosion resistance, aluminum automotive lightweight ideal material of choice.

Second, the increase in passenger comfort and safety for. Of motor vehicles is not to reduce capacity of aluminum alloy case reduce vehicle weight, body weight reduction, the car more stable and comfortable. Due to the absorption of aluminum can is good, has obvious advantages in terms of crash safety, deformation of the front part of the car at the time of the collision will have wrinkles, can absorb a great deal of impact, protecting the back of driver and passenger.

Third, easy to recycle aluminum. Aluminum products in use almost no corrosion or only slight corrosion occurs, in the conventional materials used in industry, aluminum recycling value rate is highest. Aluminum-aluminum-products-use-recycled aluminum ingots and then processed into aluminum recycling process, aluminum consumption is only about 5%, its regeneration performance than any commonly used metals are high.
