As the demand for energy shortages and rising oil prices, many automobile manufacturers are trying to vehicle weight, use of aluminum and other light metal on the car for "downsizing" in order to achieve the objective of saving fuel.
Gap reserves potential
According to reports, closely related to the motor vehicle fuel consumption and vehicle weight, vehicle weight reduced by 100 kg, can save 0.3 liters of gasoline per hundred kilometers. Thus, automotive lightweight material, accurate development trend. Aluminum alloys and magnesium alloys because of its light weight, corrosion resistance, easy to mold, and be treated as ideal material of manufacturing automobile parts. China's demand for aluminum alloy castings of automobile year is 400,000 tons, and is an annual rate of 10%, the market prospects. Automotive aluminum casting industry in China is in the ascendant, with great development potential.
