Farmer’s Copper Ltd. inventories C10100 (OFE) and C10200 (OFHC) copper round rod ½” to 6” diameter. C101 and C102 copper is produced by melting and pouring copper in the presence of carbon or carbonaceous gases so the oxygen can be absorbed. This high purity and absence of deoxidizers account for its average conductivity of 101% IACS. Oxygen-Free High Conductivity Copper (OFHC) 102 is free from hydrogen embrittlement when heated in a reducing atmosphere.
