Powder Metallurgy *P/M is a highly developed method of manufacturing reliable ferrous and nonferrous parts. Made by mixing elemental or alloy powders and compacting the mixture in a die, the resultant shapes are then sintered to bond the particles metallurgically. *P/M is a cost effective production method used to produce complex parts at or very close to, final dimensions. As a result, only minor, if any, machining or finishing operations are required. Advantages of P/M *Eliminates or minimizes machining *Eliminates or minimizes scrap losses in production *Close dimensional tolerances *Permits a wide variety of alloy systems *Good surface finishes *Can control part density *Suitable for complex or unique shapes which would be impractical or impossible with other processes Limitations *Most P/M parts weigh less than 5 pounds (2.27kg) *Corrosion resistance can be lower *Tensile strength can be lower *Formability of P/M parts can be lower P/M Production Process
