Over the past twenty years, the world automobile industry the application of aluminum castings are on the increase, according to statistics, the world’s aluminum production increase by more than 3% annually, in the production of aluminum castings, 60% – 70% of the aluminum used in automobile manufacturing, in the auto industry developed countries, automotive aluminum casting account for much of the production of various kinds of aluminum castings, such as Japan, 77% of aluminum die castings are automotive castings.
The benefits brought by the increase in the amount of automotive aluminum are mainly reflected in the following aspects:
1. Promote vehicle lightweight, energy saving and consumption reduction, and environmental protection
10% reduction in the weight of a 1300kg car can reduce fuel consumption by 8%, or 0.7kg of gasoline for every 100km traveled.
2. Aluminum alloy parts can be recycled to further save energy
Usually the recovery rate of aluminum alloy is not less than 85%, 60% of the automotive aluminum alloy comes from the recycling of waste materials, to 2010, this value has risen to about 95%.
3. Increase corrosion resistance and prolong service life
A dense oxide film can be formed on the surface of aluminum and its corrosion resistance and oxidation resistance are much higher than that of steel materials. At the same time, aluminum alloy has excellent surface treatment performance, suitable for oxidation coloring, powder spraying, paint and other surface treatment processes.
4. It helps to improve the balance and safety of car driving
Using aluminum alloy can make the wheel vibration decreases, which can use lighter rebound buffers, in addition, due to the use of aluminum alloy material is in the case of not reduce car volume reduce automobile weight, thus make the car more stable, when hit by aluminum alloy structure can absorb and disperse more energy, and therefore more safe and comfortable.
Typical application of aluminum alloy die casting in automobile
The high-tech passenger car transmission shell produced by low-pressure aluminum die casting process is equipped with two models of 2013 cars in batches.
High stress aluminum die casting parts, with good mechanical properties
Aluminum die casting has excellent performance in weight reduction:
