Pure Copper welded wire mesh rolls is stocked to EN 10223-7 / ASTM A740. 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 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.

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.
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.
