Powder metallurgy products are mostly made of metal. Powder metallurgy is a process technology that uses metal or metal powder as raw materials to manufacture metal materials, composite materials and various types of products through forming and sintering. Generalized powder metallurgy products include iron tools, cemented carbide, magnetic materials and powder metallurgy products. The narrow sense of powder metallurgy products industry only refers to powder metallurgy products, including powder metallurgy parts, oil-bearing and metal injection molding products.

Powder metallurgy technology has a series of advantages such as obvious energy saving, material saving, excellent performance, high product precision and good stability, which is very suitable for mass production.

Powder metallurgy has unique chemical composition and mechanical and physical properties, which can not be obtained by traditional casting methods. Powder metallurgy technology can be directly used to manufacture porous, semi-dense or fully dense materials and products, such as oil-bearing bearings, gears, cams, guide rods, cutters and so on. This is a process with less cutting.

Powder metallurgy-related enterprises are mainly applicable to the production and research of spare parts in automobile industry, equipment manufacturing industry, metal industry, aerospace, military industry, instruments and meters, hardware tools, electronic household appliances and other fields, the production of related raw materials and auxiliary materials, and the manufacture of various powder preparation equipment and sintering equipment. Products include bearings, gears, cemented carbide tools, molds, friction products, etc.

Powder metallurgy is similar to the production of ceramics and belongs to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used to prepare ceramic materials.
