The development of aluminum alloy castings in automobile

The history of using aluminium alloy instead of cast iron to produce automobile parts dates back to the 1940s. At that time, a few European car plants, such as Italy's Fiat, developed aluminium alloy intake pipes and cylinder heads and began to produce small quantities.

In the 1950 's, Australia introduced the low pressure casting technology of a UK company to produce aluminium castings for automobile. Former west, meanwhile, the company has made further improvement of low pressure casting technology, produced aluminium alloy parts with complicated structure. Gm also begins mass production of aluminum alloy castings for car use, such as air cooling cylinder head, crankcase, engine rear cover, and etc..

Since the 1960 's, due to the development of high pressure die casting technology, the application of light metal based on aluminum alloy in automobile has been greatly increased, thus layed the foundation of the modern automobile industry extensively adopting aluminum alloy casting to alleviate the self weight of the automobile.

The development of aluminum casting in automobile industry is the most prominent in Japan. In the early 1970s, many Japanese automobile companies began to develop and expand the application of aluminum alloy in automobile engines, and began to use aluminum castings instead of cast iron to produce the intake pipe and cylinder head, and began to produce a small number of aluminum engines.

Since the 1970 's, the industrialized developed countries of the world have made various strict demands on the quality of automobile in the background of energy saving and low carbonization, so as to make auto parts of aluminum alloy as the strategic direction of light weight reduction of automobile. As a result, the world's aluminum die-casting industry is developing rapidly, and the die casting industry is more closely related to the automobile industry.

Over the past 20 years the use of aluminum castings in the world automobile industry has been increasing. It is estimated that total production of aluminum castings worldwide increases at a rate of more than 3% per year. While in the total production of aluminium die castings, 60% to 70 % of aluminium castings are applied for automotive manufacture because of which the production and application of aluminum castings of the world is closely linked to the development of automobile manufacturing industry.

We believe that with the more and more extensive applications of aluminum alloy casting in automobile, it will promote the common development and progress of casting process and automobile industry.
