摘要：Non ferrous casting is the fundamental material for the development of the national economy. The vast majority of professions such as aviation, aerospace, sedans, mechanical processing and production, electricity, communication, construction, and home appliances are based on non ferrous metal materials. With the rapid progress of modern chemical engineering, agriculture, and science and technology, the position of non-ferrous casting in human development is becoming increasingly important. It is not only an important strategic material and means of production in the world, but also an essential consumer material in human life.
