Product description
Porous metal cups for precision filtration and controlled flow applications
Porous metal cups are precision-manufactured components produced from sintered metal powders, creating a rigid structure with interconnected porosity for controlled gas and liquid flow. These components are engineered for demanding industrial, analytical and OEM systems requiring consistent filtration performance and mechanical durability.
Porous metal cups can be manufactured from a wide range of high-performance alloys including 316L stainless steel, 904L stainless steel, Nickel 200, Monel 400, Inconel 600, Hastelloy C-276, Hastelloy C-22 and Hastelloy X. This broad material availability ensures compatibility with corrosive chemicals, high-temperature environments and aggressive process media.
Function and performance
Porous metal cups operate by allowing fluids or gases to pass through a network of uniformly distributed pores while retaining contaminants and stabilising flow characteristics.
This structure provides:
precise and repeatable filtration efficiency
controlled permeability and flow resistance
uniform pore distribution
low pressure drop across the media
mechanical stability under differential pressure
The sintered construction eliminates weak points and ensures structural integrity even in high-pressure or vibration-intensive applications.
Material options
Porous metal cups are available in the following materials to meet a wide range of chemical and thermal requirements:
316L Stainless Steel – general industrial applications with good corrosion resistance
904L Stainless Steel – enhanced resistance to chlorides and aggressive media
Nickel 200 – excellent performance in caustic and high-purity hydrogen environments
Monel 400 – strong resistance to seawater and marine environments
Inconel 600 – suitable for elevated temperature and oxidising conditions
Hastelloy C-276 – exceptional resistance to highly corrosive chemicals
Hastelloy C-22 – superior pitting and crevice corrosion resistance
Hastelloy X – high temperature strength and oxidation resistance
The wide alloy selection allows optimisation based on fluid chemistry, temperature, pressure and environmental conditions.
