Wedge Wire Screen Tubes woven or fabricated in Pure Copper (C11000) keeps its dimensional specification to Industry standard (V-wire); the alloy determines corrosion behavior (good atmospheric resistance with a stable patina; outstanding conductivity) and the service temperature limit (approx. +200 °C). Both are covered below with the full specification table.
Why Choose Pure Copper for Wedge Wire Screen Tubes
The EMI/RFI shielding and Faraday-cage mesh material. For wedge wire screen tubes, 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 wedge wire screen tubes 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.
