silicon metal for aluminum

With special property, silicon metal for aluminum. Casting aluminum ingots is basically silicon aluminum alloy, which contains certain percentage of Si. Aluminum-silicon alloys, also known as "silicon aluminum" or "silumin". Silicon metal for aluminum can improve casting performance and wear resistance, small coefficient of thermal expansion, and has the largest variety in cast aluminum alloys. The alloy with the largest amount is 10% to 25% silicon metal for aluminum. Sometimes added 0.2% ~ 0.6% magnesium silicon aluminum alloy, widely used in structural parts, such as shells, cylinders, car wheels, boxes and frames. Sometimes adding appropriate amounts of copper and magnesium can improve the mechanical properties and heat resistance of the alloy. Such alloys are widely used to make pistons and other components.

Anyang Huatuo Metallurgy analyzes and predicts that due to the ever-increasing automobile demand of countries in the world, and the requirement for car body weight reduction and energy consumption reduction, magnesium alloys will be used in the automotive industry with a high proportion of total weight, and global auto aluminum alloy wheels will Continue to grow at 8.6%. So dose the market demand of silicon metal for aluminum.

In recent years, many large global automobile production companies have set up factories in developing countries in the Asia-Pacific region to reduce production costs, making full use of talents and cheap labor in developing countries. In 2011, major manufacturers in Western European and North American countries carried out outsourcing production operations in China. And before that, China already is the largest producer of silicon metal for aluminum. As a result, compared with developed economies, the proportion of global aluminum wheel rim industry in developing countries is rapidly growing, which also covers South Korea,India,Taiwan province of China and other places.
