Less Waste - Better Use of Material

Powder Metallurgy 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 or heated in a controlled-atmosphere furnace. 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.

Faster, More Accurate Production

The P/M process is cost effective in producing simple or complex parts at, or very close to, final dimensions in production rates, which can range from a few hundred to over a thousand parts per hour. As a result, only minor, if any, machining is required. P/M parts also may be sized for closer dimensional control and/or coined for both higher density and strength.

More Options for Greater Value

Additionally, both ferrous and nonferrous P/M parts can be oil impregnated to function as self-lubricating bearings. P/M parts can be resin impregnated to seal interconnected porosity and then plated, infiltrated with a lower melting point metal for greater strength and shock resistance, and heat treated to attain a higher strength and hardness.

Greater Versatility and Flexibility

Numerous industries apply the basic versatility of P/M. Reliable P/M designs now serve the automotive, business machine, aerospace, electrical and electronic, small and major appliance, agricultural, and hand and power tool industries.

In addition to providing specialized parts which are very difficult and expensive to make by any other process, P/M also offers an effective alternative to machined parts, casts, and forgings.
