Aluminum alloy is very suitable for the characteristics of the sand casting process, because the sand casting of aluminum alloy besides has the characteristics of ordinary sand casting, also has the following unique advantages: aluminum alloy under the pouring temperature, the bubble shape of breakdown products mainly for aerosol material such as hydrocarbons and benzene, they hedge type forming extremely easy oxidation of liquid aluminum alloy has the natural protection.

In addition, the negative pressure molding of dry sand is adopted to avoid the contact between liquid aluminum alloy and the moisture in molding sand and the casting defects caused thereby.

Applications of Aluminum alloy Parts

The Aluminum alloy parts could be applied to transport, construction, aircraft industry, building and architecture.

For example, the construction turns to cast parts for road barriers. Aluminum castings are even used by hardware fittings in building and architecture.
