Aluminum castings refer to equipment and components made of pure aluminum or aluminum alloys obtained by casting. Generally, sand molds or metal molds are used to pour heated liquid aluminum or aluminum alloy into the mold cavity, and the obtained aluminum parts or aluminum alloy parts of various shapes.

Since the end of the 1980s, many automobile manufacturers in Europe, the United States, and Japan have cooperated with aluminum companies to strengthen research on aluminum automobile bodies and have achieved encouraging results. In 1995, the German Audi company first began to mass-produce aluminum bodies.

Cast iron still occupies a place in automotive materials because of its many advantages in performance and cost. The progress of cast iron material makes its application in automobile appear new bright spots.

Although the consumption of steel materials has decreased year by year, the consumption of high-strength steel has increased considerably. High strength structural steel conducive to the lightweight of cars.

In the competition with non-ferrous alloys and polymer materials, iron and steel materials continue to give full play to their advantages of low price and mature technology.

The application prospect of plastics in the automotive industry is also promising. At present, the plastic consumption of many cars in the world has exceeded 120 kg / vehicle, and that of individual models is even higher.
