Aurubis Cu-OFE (oxygen-free electronic) is an oxygen-free, high conductivity copper with 99.99% minimum copper. It offers the advantages of both electrolytic tough pitch (ETP) copper and phosphorus deoxidized (DHP) copper. Its high purity, with less than 5 ppm (0.0005%) oxygen, and the absence of deoxidizers accounts for minimum 101% IACS electrical conductivity as well as no susceptibility to hydrogen embrittlement. Cu-OFE has very good formability and can be soldered and welded, which makes it superior to Cu-ETP in these aspects. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming and machining. Filing Code: Cu-907. Producer or source: Aurubis AG.
