Farmer’s Copper Ltd. maintains inventory of C10100 OFE Copper in variety of shapes such as sheet, plate, and round rod. C101 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 alloy (OFHC) 101 is free from hydrogen embrittlement when heated in a reducing atmosphere. C10100 can be certified to the percent of impurities in its composition, whereas C10200 is uncertified.
