Powder metallurgy is an industrial technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by forming and sintering, to produce metallic materials, composite materials, and various types of products. Powder metallurgy technology has been widely applied in transportation, machinery, electronics, biology, new energy, information technology, and nuclear industries, becoming one of the most dynamic branches of new materials science. Powder metallurgy technology possesses a series of advantages, including significant energy saving, material saving, excellent performance, high product precision, and good stability, making it very suitable for mass production. Furthermore, some materials and complex parts that cannot be prepared using traditional casting and machining methods can also be manufactured using powder metallurgy technology, thus attracting significant attention from industry.
The powder metallurgy products industry in a broad sense encompasses iron and stone tools, cemented carbide, magnetic materials, and powder metallurgy products. In a narrow sense, the powder metallurgy products industry refers only to powder metallurgy products, including powder metallurgy parts (which account for the vast majority), oil-impregnated bearings, and metal injection molded products.
