The development trend of the light alloy casting

As is known to all, reduce the energy consumption and reduce environmental pollution, and save the earth's limited resources are facing today's people a very important and urgent task. In automobile, 3 c products such as the total trend of lightweight, can be expected, in the next 10 years in our country, non-ferrous metal casting market, especially in light metal casting market, there will be a substantial development.

 

Various casting producer of non-ferrous metal casting yield ratio of casting production is between 14-21%, which accounts for the proportion of the total output of aluminum, magnesium alloy castings in 13 to 19%, the highest Italy reached 38% and 28% respectively. And only 7.4% in mainland China non-ferrous metal castings, aluminum, magnesium alloy castings was 5.7% (above) according to annual production of 2000, 24.7% and 20.6% respectively in Taiwan (according to 1998 statistics). Thus it can be seen in the future of aluminum, magnesium alloy castings in China market still have considerable space for development. Attaches great importance to our government and industry association casting industry development opportunities and severe challenges, and take the corresponding countermeasures. The following is the direction of the aluminum alloy casting technology development and progress of the industrialization of magnesium alloy in China a brief analysis.

 

1. Aluminum alloy casting technology development direction

 

Aluminum alloy is the most commonly used material in light metal materials, developed countries are now more than 90% of aluminum castings used in auto industry, aluminum alloy castings for automotive lightweighting plays an important role. But as the production of aluminum alloy castings, which should be solved to meet the requirements of lightweight title is still a lot.
