Copper Washer:12mm x 18mm x 1.5mm - DIN 7603A

This copper washer is a flat, circular fastener component manufactured from solid copper to DIN 7603A standards. It features an outer diameter of 18mm and a nominal bore of 12mm with a thickness of 1.5mm. The material provides good corrosion resistance and electrical conductivity, making it suitable for applications where non-magnetic or conductive properties are required. Buyers typically select this type of washer for its durability in moist environments and its ability to maintain joint integrity without galling. When selecting this component, ensure the 12mm bore fits your bolt shank and that the 18mm outer diameter provides sufficient bearing surface for the mating part. The 1.5mm thickness should be verified to match the available space in your assembly.
