Oxygen-free high-conductivity copper OFHC

Electrical and other properties of copper render it the most widely used metallic conductor. Oxygen-free high-conductivity (OFHC) copper, having extremely low oxygen and other impurity contents, is produced for many electrical applications. Aluminum, having a conductivity only about one-half that of copper, is also frequently used as an electrical conductor. Silver has a higher conductivity than either copper or aluminum however, its use is restricted on the basis of cost. 

Pure or elemental copper, also known as oxygen-free high-conductivity copper (OFHC), has a low annealing point. When annealed, the mechanical...
