Construction technology of powder metallurgy technology in metallurgical industry of our country is use a very wide range of technology, mainly because of powder metallurgy technology is indeed a very practical technology of metallurgy, powder metallurgy technology can solve many other metallurgical technology can not solve the problem, the advantages of powder metallurgy technology mainly include:
The first article is now the vast majority of refractory metals and compounds, fake alloys, porous materials can only be manufactured by powder metallurgy method;
Second is now the powder metallurgy technology can be pressed into the final size of the compact, and not need or need less subsequent mechanical processing, it can greatly save metal, reduce product cost. Products manufactured by powder metallurgy, metal loss only 1-5%, and general casting method used in the production, the loss of metal may will reach 80%.
The third is now due to the technology of powder metallurgy in the production process of the material does not melt materials, not mixed with impurities caused by crucible and deoxidizing agent and sintering general in vacuum and in a reducing atmosphere, not afraid of oxidation nor to any material pollution, so it is for preparation of high purity materials.
Fourth is now the powder metallurgy method can guarantee the accuracy and uniformity of the composition ratio of the material.
Fifth is now the powder metallurgy suitable for the production of the same shape and the number of products, especially gear and other high processing costs of products, powder metallurgy process can greatly reduce production costs.
