Powder metallurgy is the preparation of metal powder and the process of forming and sintering of powdered metal or non-metallic powder mixtures of products, processing methods, can the system access to the ordinary melting method is difficult to manufacture special materials, but also manufacturing variousprecision mechanical parts, the provincial labor and materials. However, the high cost of molds and metal powder should not be used in small batch or product size is too large. Powder metallurgy materials and process compared with traditional materials technology, has the following characteristics:

nd the process of forming and sintering of powdered metal or non-metallic powder mixtures of products, processing methods, can the system access to the ordinary melting method is difficult to manufacture special materials, but also manufacturing various precision mechanical parts, the provincial labor and materials. However, the high cost of molds and metal powder should not be used in small batch or product size is too large. Powder metallurgy materials and process compared with traditional materials technology, has the following characteristics:

1, powder metallurgy process is lower than the melting point of the matrix metal, so you can get the melting point, density difference between the variety of metals, metal and ceramic, metal and plastic multiphase heterogeneous special function compound materials and products .

2, improve the performance of materials. Special method of preparation of small metal or alloy powder solidified fast, fine grain and uniform to ensure that the organization of the material is uniform, stable performance, and good cold, heat processing performance, and the powder particles from the alloy elements and content limit can be increased to strengthen the phase content, the development of new materials system.

3,The use of various forming processes, forming the powder raw material directly to the less margin, margin rough or net-shaped parts, and a significant reduction in machining. Improve material utilization and reduce costs.
