Characteristics and application of nonferrous metal precision casting process
- Aug 22, 2018 -

At present, nonferrous metal precision casting mainly includes three types of metal casting, namely aluminum, magnesium and copper. Among them, aluminum castings are mainly used in the automobile manufacturing industry. Although aluminum metal precision castings are more expensive than black metal castings, they have a large market demand because they can reduce the weight of the car and improve fuel efficiency.


For the effective casting of aluminum and magnesium, the main casting process is die casting. Magnesium alloy castings are used in aerospace, automotive and electronic applications. The main advantage is light. Special problems arise in the melting process of copper and copper alloys. For example, copper water will inhale oxygen and hydrogen, and will produce pores on the casting after solidification. The copper melt dissolves oxygen and hydrogen, and these components leave pores on the casting after curing.


In short, metal precision casting is widely used in machinery manufacturing, aviation, automotive, construction and other industries. Moreover, non-ferrous metal castings account for a large share of the use of non-ferrous materials (sometimes nearly half), forming a large and complex series of cast alloys.
