Oxygen free copper is a purer form of copper that has less oxygen within its structure. Because of this property such copper is very resistant to oxidation (corrosion) and would be ideal for wiring home speakers, especially if the speakers are not easily accessible, as in flush wall or ceiling mounted speakers.Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below.
