Engineered Porosity PM Process

Engineered Porosity PM

While conventional PM processing sinters parts to 82%-88% of the theoretical density, Engineered Porosity materials are carefully processed to achieve densities from 30%-80% of the theoretical density. This process provides an interconnected network of pores bounded by high strength, metallurgically bonded stainless steel.

Engineered Porosity components, molded from a controlled mixture of metal powder and sacrificial 'pore-formers', are sintered in closely calibrated, high-temperature, hydrogen atmosphere furnaces. Controlling the chemistry and size of the 'pore-formers' as well as the size of the metal powders provides an almost infinite variety of porous networks. This diversity explains the variety of creative applications for this process.
