For welded wire mesh rolls in Pure Copper, the controlling selection factors are the media being filtered, the cleaning regime and the service temperature. The grade data for Pure Copper is summarized below together with every specification supplied.
Why Choose Pure Copper for Welded Wire Mesh Rolls
The EMI/RFI shielding and Faraday-cage mesh material. For welded wire mesh rolls, 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 |
Corrosion Behavior in Filtration Service
Copper and brass welded wire mesh rolls resist atmospheric corrosion and fresh water well, tarnishing to a stable patina. Avoid ammonia and ammonium compounds (stress-corrosion cracking of brass) and strong oxidizing acids. In marine service, phosphor bronze outperforms plain brass.
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.
