Material page for hexagonal hole perforated sheet in Pure Copper. The EMI/RFI shielding and Faraday-cage mesh material. Covers the grade designation (C11000), corrosion and magnetic behavior, cleaning and compatibility notes, and the specifications available.
Why Choose Pure Copper for Hexagonal Hole Perforated Sheet
The EMI/RFI shielding and Faraday-cage mesh material. For hexagonal hole perforated sheet, 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.
