What are the advantages of using aluminum alloy?

(1) Obvious effects of weight reduction and energy saving. Aluminum has good mechanical properties, its density is only 1/3 that of copper and iron, and it has good thermal conductivity, second only to copper, and its machining performance is 4.5 times higher than that of iron, and the naturally formed oxide film on its surface has good corrosion resistance Therefore, aluminum has become an ideal material for realizing automobile lightweight.

(2) Passenger comfort and safety are improved. Aluminum alloy cars reduce the weight of the car without reducing the capacity of the car, reduce the body weight*, and make the car more stable. Due to the good energy absorption of aluminum profile, it has obvious advantages in crash safety performance. The deformation zone at the front of the car will produce wrinkles during a collision, which can absorb a large amount of impact force, thereby protecting the driver and passengers behind.

(3) Aluminum is easy to recycle. Aluminum products rarely corrode or only slightly corrode during use. Among the conventional materials used in industry, the recovery value rate of aluminum is high. In the recycling process of aluminum profile-aluminum product-use-recycling of recycled aluminum ingots-reprocessing into aluminum profile, the loss of aluminum is only about 5 percent, and its recycling performance is higher than that of any common metal.
