Round and Square Sintered Metal Powder Filter Discs for Flow Control and FiltrationRound and Square Sintered Metal Powder Filter Discs for Flow Control and Filtration

Sintered Metal Powder Discs

CMI Sintered Metal Powder Filter Discs are high-performance porous components designed for precise filtration and flow control in extreme environments. Manufactured via isostatic pressing and high-temperature vacuum sintering, these discs feature a rigid, uniform structure with precise pore distribution and exceptional mechanical strength.

We offer full customization in round, square, and complex geometries (OD 4–400mm) using resilient materials like 316L Stainless Steel, Titanium, and Hastelloy. Capable of withstanding temperatures up to 900°C and providing filtration ratings from 0.3 to 100 μm, CMI discs ensure zero media migration and high permeability. They are the ideal choice for decarbonization, catalyst recovery, and system protection in pharmaceutical, petrochemical, and high-purity gas applications.

Category:
Round, Square, and Custom-Shaped Porous Metal Components
CMI manufactures sintered metal powder filter discs in a wide range of materials, sizes, and geometries for industrial filtration and flow control applications.
