Copper Wire Mesh is used for conducting, shielding and screening with woven pure copper cloth — the go-to metal mesh for RF shielding, grounding grids, battery and electrochemical work and copper-specific screening. ASTM E2016 is the reference cited for it on drawings, datasheets and purchase orders.
What ASTM E2016 Means for Copper Wire Mesh
The dimensions in the table below are supplied to suit ASTM E2016. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Equivalent Standards
ASTM E2016 is the US counterpart of ISO 9044 for industrial woven wire cloth.
Copper Wire Mesh Dimensions

Specifying Copper Wire Mesh Beyond the Standard
- Mesh & wire: Finer mesh with heavier wire improves high-frequency shielding; coarser, thinner wire keeps it flexible and light.
- Purity: C11000 ETP (99.9 % Cu) for conductivity; specify C10200 oxygen-free where it will be brazed or used in hydrogen.
- Temper & finish: Soft annealed for forming around frames; bright or tinned to slow tarnish on contact faces.
When Copper Wire Mesh Is Not the Right Choice
Not a structural mesh and not suitable for drinking water, ammonia or acidic process streams — choose stainless steel there.
