Advantages of powder metallurgy

1. Special materials can be processed. Materials and methods of powder metallurgy can make refractory metals and compounds, pseudo alloys and porous materials.

2, save metal and reduce cost. Because powder metallurgy can be pressed into final size blanks, and no mechanical processing is needed. The loss of metal produced by this way is only 1 to 5%, while the general processing will consume 80% of metal.

3, high purity materials are made. In the process of powder metallurgy, the non melting material will not be mixed with the impurities brought by other materials, and the sintering is carried out in the vacuum and reduction atmosphere, not afraid of oxidation and no pollution material. Therefore, the purity of the products is relatively high.

4. The distribution of materials is correct. Powder metallurgy method can ensure the correctness and uniformity of material composition in proportion.

5. Mass production reduces the cost. Powder metallurgy is suitable for the production of a large number of uniform shape products, such as gear and other expensive products, which can greatly reduce the production cost.
