Powder metallurgy is an industrial technology for producing metal powders or using metal powders (or mixtures of metal and non-metal powders) as raw materials, which are then shaped and sintered to produce metal materials, composite materials, and various types of products. Powder metallurgy technology has been widely applied in transportation, machinery, electronics, aerospace, weaponry, biology, new energy, information, and nuclear industries, becoming one of the most dynamic branches in new materials science. Powder metallurgy technology offers a series of advantages such as significant energy saving, material saving, excellent performance, high product precision, and good stability, making it very suitable for mass production. In addition, some materials and complex parts that cannot be prepared by traditional casting or machining methods can also be manufactured using powder metallurgy technology, which has earned it significant attention from the industrial sector.
The broad definition of the powder metallurgy products industry includes cemented carbide tools, hard alloys, magnetic materials, and powder metallurgy products. The narrow definition of 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 molding products.
