Our material selection process considers media compatibility, chloride content, acid concentration, oxidation potential, operating temperature, cleaning methods, and mechanical stress to provide long service life with predictable performance.
To maintain strict upstream quality control, CMI also produces selected sintering-grade metal powders in-house. This vertical integration allows tighter control over particle size distribution, powder purity, morphology consistency, and batch-to-batch stability—critical factors that directly influence pore structure, permeability, and final filter performance.

Core Material Platforms
316L Stainless Steel (The Versatile Standard)
The most widely used industrial alloy for porous metal filtration. Offers excellent corrosion resistance, strong mechanical integrity, and good weldability for general service conditions.

Titanium (Extreme Corrosion Resistance)
Provides outstanding resistance to chlorides, seawater, oxidizing media, and many aggressive process fluids. Lightweight with high strength and excellent biocompatibility.
- Seawater desalination
- Hydrometallurgy
- Ozone aeration systems
- Pharmaceutical decarbonization filtration
- High purity liquid processes
Hastelloy C276 / C22 (High Acid Resilience)
Premium nickel-based alloys engineered for severe acidic and oxidizing environments. Maintains structural integrity under harsh chemical attack where stainless steel may fail.
- Fine chemical production
- Pesticide manufacturing
- Strong acid filtration systems
- Corrosive solvent recovery
Monel 400 (Specialist for Fluorine & Alkali)
Excellent resistance to hydrofluoric acid, alkalis, seawater, and many reducing environments. Known for toughness and durability in difficult service.

Inconel 600 / 625 (Ultra-High Temperature Service)
Designed for elevated temperature operation with superior oxidation resistance and mechanical strength. Suitable for continuous thermal cycling and aggressive hot gas service.
- Hot gas filtration
- Petrochemical cracking
- Thermal process equipment
- Nuclear power applications
- High temperature exhaust systems
Why Powder Quality Matters
The performance of porous metal media begins at powder level. Irregular particle shape, contamination, or unstable particle sizing can cause inconsistent pore networks, lower strength, and unpredictable pressure drop. By controlling powder production internally, CMI improves repeatability from raw material to finished porous component.
CMI Engineering Support
Beyond material supply, CMI assists customers in selecting the correct alloy based on corrosion chemistry, process temperature, pressure load, cleanability, and total lifecycle cost. We help prevent premature failures caused by incorrect material selection.
