C103 (OF) is a commercially pure grade of oxygen-free copper manufactured by pouring in a protective gas atmosphere or vacuum. The absence of oxygen ensures high levels of elecrical conductivity and low susceptibility to embrittlement when heated in a reducing atmosphere. This makes the alloy suitable for various types of welding.
