Engineered Porosity PM Benefits

Engineered Porosity offers a variety of benefits derived from the unique characteristics provided by this process. Well-informed designers utilize the wide potential of porous parts to develop creative solutions for challenging situations.

More specifically, engineers are able to design components with:

Precise Permeability
Permeability, the measure of how much gas or fluid will pass through a part in a given time under a known pressure, can be maintained over a porosity range of 15 to 20%.

Unique Flow Characteristics
Engineered Porosity components can be designed to allow the flow of vapors while restricting or preventing the flow of liquids. This provides an excellent benefit for designers working with propane or liquid refrigerants, as well as applications requiring protection from water.

Controlled Flow Rates
Engineered Porosity components offer a significant advantage when compared with single hole, small orifice flow controllers. Providing precise flow control that ranges from micro-leaks to high volumes, the multitude of porous pathways minimizes potential blockage.

Superior Corrosion Resistance
The corrosion resistance of Engineered Porosity components is similar to that of the base metal. Frequently 316 stainless steel and alloys such as Hastelloy and Monel have been used for demanding applications.

Fine-Tuned Filtration
The mean pore size, defined by our standard system based on theoretical mean pore size, ranges from 3 microns to 250 microns. This allows effective filtration down to 1 micron.

Superior Strength
Engineered Porosity uses high temperature, controlled atmosphere sintering to achieve strong metallurgical bonds. This provides components with outstanding rigidity, shock resistance, and the ability to be 'cleaned'.
