1. The vast majority of refractory metals and their compounds, pseudo alloys, and porous materials can only be manufactured by powder metallurgy.

2. Because powder metallurgy can press the final size of the blank without requiring or rarely requiring subsequent machining, it can greatly save metal and reduce the cost of the finished product. Therefore, when the powder metallurgy method is used to manufacture the product, the metal The loss is only 1-5%, and the metal loss can reach 80% when the general casting method is used for production.

3. Because the powder metallurgy process does not melt the material during the material production process, and is not afraid of doping impurities from the crucible and deoxidizer, the sintering is generally carried out in a vacuum and reducing atmosphere, which is not afraid of oxidation and will not cause damage to the material. Any pollution, so high-purity materials can be produced.

4. Powder metallurgy can ensure the correct and even distribution ratio of materials.

5. Powder metallurgy technology is suitable for the production of products that are formed on the same day and in larger quantities, especially gears and other products with higher processing costs. The use of stainless steel powder metallurgy manufacturing capabilities can greatly reduce the cost of production.
