Product description
Porous metal sheets for filtration, diffusion and flow distribution
Porous metal sheets are precision-manufactured planar elements produced from sintered metal powder to form a uniform matrix of interconnected pores. The sheets combine mechanical strength with controlled permeability for use in gas and liquid filtration, flow distribution, vapor diffusion, and fluid control applications.
These sheets are ideal for engineered systems where a robust, all-metal, and chemically resistant medium is required for scalable process performance.
Material options
Porous metal sheets are available in a broad range of corrosion-resistant alloys, enabling selection based on process chemistry, temperature and pressure needs:
316L Stainless Steel – general industrial corrosion resistance
904L Stainless Steel – enhanced resistance to chlorides
Nickel 200 – high-purity and caustic environments
Monel 400 – marine and chloride environments
Inconel 600 – high temperature oxidation resistance
Hastelloy C-276 – superior chemical corrosion resistance
Hastelloy C-22 – enhanced resistance to pitting and crevice corrosion
Hastelloy X – high temperature strength and oxidation resistance
Filtration and flow characteristics
Porous metal sheets operate through depth filtration and controlled permeation. Process media passes through the interconnected pore network, where particles and contaminants are captured according to pore size while maintaining predictable flow resistance and low pressure differentials.
Key benefits include:
uniform pore structure for consistent performance
controlled permeability and flow distribution
mechanical integrity at elevated temperatures and pressures
chemical compatibility with aggressive fluids and gases
scalable dimensions for large filter panels or modular assemblies
