Powder metallurgy is the production of metal powder metallurgy or the use of metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, for the production of metal materials and composite materials And the technological process of various products. Powder metallurgy and ceramics have similarities, and both belong to powder sintering technology. Therefore, some new powder metallurgy technologies can also be used to produce ceramic materials. Thanks to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a key role in the development of new materials.

Powder metallurgy includes milling and products. Among them, milling is mainly a metallurgical process, which is consistent with its literal meaning. Powder metallurgy products often go far beyond materials and metallurgy, and are often interdisciplinary (materials and metallurgy, mechanical engineering and mechanics, etc.) technology. Especially modern 3D printing based on metal powder, integrating mechanical engineering, CAD, reverse engineering technology, multi-layer manufacturing technology, numerical control technology, material science and laser technology, transforms powder metallurgy technology into modern comprehensive technology, covering more disciplines .
