Powder metallurgy is an industrial technology used to prepare metal powder or metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering to obtain metal materials, composite materials and various types of products. At present, powder metallurgy technology has been widely used in transportation, machinery, electronic equipment, aerospace, weapons, biology, new energy, information and nuclear industry, and has become one of the most dynamic branches of new materials science. Powder metallurgy technology has a series of advantages such as significant energy-saving effects, materials, excellent performance, high precision and stability of products, and is very suitable for mass production. In addition, some materials and complex parts that cannot be prepared by conventional casting methods and machining methods can also be manufactured by powder metallurgy technology, so they have attracted widespread attention in the industry.

The broad powder metallurgy product industry includes iron and stone tools, cemented carbide, magnetic materials and powder metallurgy products. The narrow powder metallurgy products industry refers only to powder metallurgy products, including powder metallurgy parts (most), oil-containing bearings and metal injection molding products.

Powder metallurgy includes milling and product. Among them, milling is mainly a metallurgical process, which is literally consistent. Powder metallurgy products usually go far beyond the scope of materials and metallurgy, and usually involve multiple disciplines (materials and metallurgy, machinery and machinery, etc.). In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, materials science, and laser technology, making powder metallurgy product technology a modern integrated technology that spans more disciplines.
