Powder metallurgy | Britannica

Powder metallurgy, fabrication of metal objects from a powder rather than casting from molten metal or forging at softening temperatures. In some cases the powder method is more economical, as in fashioning small metal parts such as gears for small machines, in which casting would involve considerable machining and scrap loss.
