Advantages:

1. Most refractory metals and their compounds, pseudo-alloys, and porous materials can only be manufactured using powder metallurgy methods. 2. Since the powder metallurgy method can be pressed into a final size compact without the need or little need for subsequent mechanical processing, it can greatly save metal and reduce product costs. When using powder metallurgy to manufacture products, the metal loss is only 1-5%, while when using general melting and casting methods, the metal loss may reach 80%.

3. Since the powder metallurgy process does not melt the material during the material production process, it is not afraid of impurities brought by the crucible and deoxidizer. Sintering is generally carried out in vacuum and reducing atmosphere, and there is no fear of mixing in impurities. Oxidation will not cause any pollution to the material, so it is possible to produce high-purity materials.

4. The powder metallurgy method can ensure the accuracy and uniformity of material composition ratio.

5. Powder metallurgy is suitable for producing large quantities of products of the same shape, especially products with high processing costs such as gears. Manufacturing by powder metallurgy can greatly reduce production costs.

Disadvantages:

1. When there is no batch size, the size of the parts must be considered.

2. The cost of molds is relatively higher than that of casting molds.

Powder metallurgy (P/M) technology is an important material preparation and forming technology. It is known as the key to solving high-tech and new material problems... High performance, low cost, and near-net forming have always been one of the important research topics for powder metallurgy workers. The powder metallurgy method can achieve less and no cutting processing of workpieces. It is an advanced technology for manufacturing parts with high efficiency, high quality, precision, low consumption and energy saving. In the 1980s, many industries, especially the automobile industry, relied more on powder metallurgy technology than ever before. Using as many high-performance powder metallurgy parts as possible was a way to improve the competitiveness of cars, especially sedans, in the market. Powerful means. High-density P/M products are the key factor to ensure excellent mechanical properties. Therefore, in order to expand the application scope of powder metallurgy P/M parts, its density must be increased to obtain powder metallurgy parts with excellent mechanical properties.
