Copper wire mesh is pliable, malleable, and has high thermal and electrical conductivity. These characteristics make it popular to use in: RFI shielding, Faraday Cages, HVAC as well as numerous electrical based applications. Copper wire mesh is able to easily bend, but still maintain its strength.
Copper mesh is a yellowish red color when first woven and will gradually patina (discolor) to a greenish/bluish called verdigris. This patina effect may be accelerated by first removing surface oil from the mesh using “Shower Power” TM or a similar mild household cleaning product. After rinsing it well, the copper will shine, but will be unprotected.
In an outdoor environment, the discoloration will become pronounced in less than six months in climates such as the seashore, or it may remain untarnished for years in desert conditions. This discoloration may be stopped by lacquering, waxing, or periodically oiling the mesh to protect it from atmospheric conditions
