Porous sintered metal – technical overview
Porous sintered metal components are engineered filtration and flow control elements manufactured from metal powder that is compacted and sintered to create a rigid, interconnected pore structure. These materials combine mechanical strength, controlled permeability and chemical resistance in a fully metallic, cleanable construction.
Unlike polymer or fiber-based filter media, sintered porous metal provides dimensional stability, high temperature capability and long service life. It is commonly used in gas filtration, liquid filtration, sparging, diffusion, pressure regulation and fluid distribution applications.
How porous sintered metal works
During the sintering process, metal powder particles are bonded together below their melting point. This creates a network of uniform, interconnected pores that allow controlled passage of gases or liquids while retaining particles based on defined micron ratings.
Depending on the application, porous metal can operate through:
- Depth filtration for particle removal
- Surface-controlled filtration
- Fine bubble gas dispersion (sparging)
- Flow restriction and pressure stabilization
- Fluid distribution and diffusion
Available materials
Porous sintered metal components are available in a wide range of corrosion-resistant and high-performance alloys, including:
- 316L stainless steel
- 904L stainless steel
- Nickel 200
- Monel 400
- Inconel 600
- Hastelloy C-276
- Hastelloy C-22
- Hastelloy X
Material selection depends on operating temperature, pressure, chemical compatibility and required mechanical strength.
Micron ratings and permeability
Porous metal is available in defined micron ratings typically ranging from 0.2 micron up to 100 micron. The selected pore size determines filtration performance, bubble size in sparging applications, and overall pressure drop characteristics.
