Oxygen-free copper: Standards & Applications

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. Oxygen-free copper is a premium grade of copper that has a high level of conductivity and is virtually free from oxygen content. The…
