Cu-OFE is a high purity, oxygen free, non phosphorus-deoxidized copper that does not contain in vacuum evaporating elements. It has a very high electrical and thermal conductivity, good welding and excellent soldering properties. It has excellent hot and cold forming properties, and a good corrosion resistance, especially in atmosphere due to a good adherence of the oxide layer. Cu-OFE can be heat treated in reducing atmosphere. The alloy is registered US EPA antimicrobial.
