Nowadays, powder metallurgy technology has been widely used in major parts manufacturing and processing enterprises. Powder metallurgical materials refer to the direct use of several metal powders or metal powders and non-metal powders without smelting and casting, and are formulated and pressed. Materials such as sintering and reprocessing. So what are the advantages of powder metallurgy?
1，Powder metallurgy is suitable for the production of a large number of products of the same shape, especially those with high processing costs such as Gears. Manufacturing by powder metallurgy can greatly reduce production costs.
2, powder metallurgy can ensure the correctness and uniformity of the composition of the material.
The vast majority of refractory metals and their compounds, pseudoalloys, and porous materials can only be manufactured by powder metallurgy methods.
4) Since the powder metallurgy process does not melt the material during the material production process, it is not afraid to mix the impurities brought about by crucibles and deoxidizers, and sintering is generally carried out in a vacuum and reducing atmosphere, and it is not afraid of oxidation or any pollution of the material. Therefore, it is possible to make high-purity materials.
5, because the powder metallurgy method can be pressed into the final size of the pressure billet, without the need or little need for subsequent mechanical processing, it can greatly save metals and reduce product costs. When manufacturing a product by powder metallurgy, the loss of the metal is only 1-5 %, while when produced by general casting, the loss of the metal may reach 80 %.
The above is the introduction of the advantages of the powder metallurgical process. The application of powder metallurgical products is very wide, from ordinary machinery manufacturing to precision instruments; From hardware tools to large machinery; From the electronics industry to electrical manufacturing; From civilian industries to military industries; From the general technology to the cutting-edge high technology, powder metallurgical technology can be seen.
