Powder Metal Parts

Powder metallurgy, otherwise known as Powder Metal Parts or P/M, is a highly developed method of manufacturing reliable ferrous and non-ferrous parts. Made by mixing elemental or alloy powders and compacting the mixture in a die, the resultant shapes are then sintered or heated in a controlled-atmosphere furnace to metallurgically bond the particles. Basically a 'chipless' metal-working process, P/M typically uses more than 97% of the starting raw material in the finished part. Because of this, P/M is an energy and materials conserving process. The P/M process is cost effective in producing simple or complex parts at or very close to final dimensions at production rates that can range from a few hundred to several thousand parts per hour. As a result, only minor, if any, machining is required. P/M parts also can be sized for closer dimensional control that essentially eliminates secondary fabrication steps and/or coined for both higher density and strength.
