Aluminum Alloy for Lightweight Car

Automobile lightweight is the development trend of the automobile industry. Statistics show that every 1% reduction in the weight of general parts of automobiles can save 1% of fuel; every 1% reduction of sports parts can save 2% of fuel. Reducing the weight of automobiles can achieve huge economic and environmental benefits.

Among the a variety of new materials used in automotive industry, aluminum alloy is the most valuable one. 5xxx and 6xxx aluminum such as 6061, 6016, 5182 and 5083 aluminum sheet are the common choices, which are mainly for the car body, engine, air conditioner, wheel hub, decorative parts, car seat, etc.

Due to the obvious lightweight effect, the amount of aluminum used in car is expanding. At present, the United States, Japan, and Germany are the countries that use the most aluminum alloy for automobiles.

Some data show that replacing the traditional steel structure with aluminum alloy structure can reduce the weight of automobiles by 30%-40%, of engines by 30%, and of wheels by 50%. In addition, automotive aluminum has good thermal conductivity and strong corrosion resistance, fully meeting the requirements of these parts.

Aluminum wheels are gradually replacing steel wheels because of their light weight, good heat dissipation, and good appearance. In the past 10 years, the global aluminum alloy automobile wheels have grown at an annual growth rate of 7.6%. 6061 aluminum plate are often used for making wheel hub.

Aluminum alloy is also widely used in other parts of automobiles. For example, General Motors uses 7021 aluminum sheet to make Smure bumper reinforcement bracket. Aluminum alloy material is also applied to automobile suspension parts, which effectively reduce the weight of corresponding parts and improve the smoothness and stability of automobile driving, such aspower transmission frames produced from 6061 forgings.
