Photo-Etched Precision Filter Disc in Pure Copper (C11000) is used for filtering, metering and diffusing fluids through thin stainless discs whose holes are chemically etched to an exact pattern — burr-free, stress-free and far more uniform than woven mesh. The alloy gives good atmospheric resistance with a stable patina; outstanding conductivity and is non-magnetic, with a practical service limit of approx. +200 °C.

Where Pure Copper Photo-Etched Precision Filter Disc Is Used
- Medical & analytical devices: inlet filters, flow restrictors and diffuser plates in pumps and analyzers.
- Fuel & gas systems: last-chance screens in valves, regulators and injectors.
- Consumer appliances: coffee machine, shaver and humidifier discs with exact flow.
- Electronics: vent discs and EMI-shielded apertures.
Ordering Photo-Etched Precision Filter Disc in Pure Copper
- Hole size vs thickness: Etched holes are normally at least the sheet thickness; thinner foil allows smaller holes.
- Pattern: Any hole shape, pitch and keep-out zone — supply a DXF so the tool matches your part exactly.
- Material: SS304/316L, nickel, copper or titanium foil from 0.03 to 0.5 mm.
Mistakes to Avoid with Photo-Etched Precision Filter Disc
- Asking for holes smaller than the foil thickness on a thick part.
- Using an etched disc where the pressure drop needs a woven or sintered layer behind it for support.
