Copper C10300 or oxygen-free electronic (OFE) copper has a minimum purity of 99.99% and contains almost no oxygen. This extremely pure grade offers electrical conductivity in the range 100–101% IACS and high thermal conductivity. Tensile strength is usually between 200 and 240 MPa, with yield strength approximating 70–90 MPa. It possesses significant ductility, with elongation mostly greater than 30%. The lack of oxygen reduces the embrittlement danger, making C10300 particularly desirable for use in cases that need high conductivity, improved corrosion resistance, and superior formability.
