Powder metallurgy is a technology that produces metal powder and uses metal powder (sometimes also adding a small amount of non-metallic powder) as raw materials, through mixing, shaping and sintering to create materials or products. It includes two parts, namely:
(1) Manufacture of metal powders (also including alloy powders, hereinafter collectively referred to as "metal powders"). (2) Using metal powder (sometimes adding a small amount of non-metallic powder) as raw materials, through mixing, shaping and sintering, materials (called "powder metallurgy materials") or products (called "powder metallurgy products") are produced.
