Pure Copper cylindrical filter cartridges is stocked to ISO 2941 / ISO 3724. The alloy provides good atmospheric resistance with a stable patina; outstanding conductivity and is non-magnetic; the practical service limit is approx. +200 °C. Property data, alloy comparison and the specification table follow.
Why Choose Pure Copper for Cylindrical Filter Cartridges
The EMI/RFI shielding and Faraday-cage mesh material. For cylindrical filter cartridges, this matters when good atmospheric resistance with a stable patina; outstanding conductivity is the controlling requirement.
Alloy Properties
| Grade designation | C11000 |
|---|---|
| Magnetic response | Non-magnetic |
| Service temperature | approx. +200 °C |
| Corrosion characteristic | Good atmospheric resistance with a stable patina; outstanding conductivity |
Cleaning & Compatibility
Clean copper-alloy mesh with mild detergent or dilute citric acid; avoid ammonia-based cleaners entirely. In contact with more noble metals in wet service the copper alloy becomes the sacrificial partner — isolate or accept the loss rate.
Comparable Alloys
Within the copper family: brass for economy and appearance, phosphor bronze for fatigue strength and marine air, pure copper where conductivity (EMI shielding) is the point. For structural filtration duties, stainless 304/316 is the usual alternative.
