Powder metallurgy is a process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, after forming and sintering, to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both belong to powder sintering technology. Therefore, a series of new powder metallurgy techniques can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problem of new materials and plays a pivotal role in the development of new materials. The material used in copper-based powder metallurgy is copper-based, and the best copper-based material is copper-tin alloy.

       Powder metallurgy includes milling and products. Among them, milling is mainly a metallurgical process, which is consistent with the literal. Powder metallurgy products are often far beyond the scope of materials and metallurgy, and are often interdisciplinary (materials and metallurgy, machinery and mechanics, etc.) technology. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, making powder metallurgy product technology a modern comprehensive technology that spans more disciplines.
