Farmer’s Copper Ltd. maintains an inventory of C10200 OFHC Copper in a variety of shapes such as: sheet, plate, rod and bus pipe. Melting and pouring copper in the presence of carbon or carbonaceous gases so the oxygen can be absorbed produce C102 copper. The high purity and absence of deoxidizers accounts 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.
