C10100 OFHC Copper is produced by the direct conversion of selected refined cathodes and castings under carefully controlled conditions to prevent contamination of the pure oxygen-free metal during processing. The method of producing OFHC copper ensures extra high grade of metal with a copper content of 99.99%. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree.

Characteristics of OFHC copper are:

· High Ductility

· High Electrical & Thermal Conductivity

· High Impact Strength

· Good Creep Resistance

· Ease of Welding

· Low Relative Volatility under high vacuum

· High Conductivity

· Ultra Low Oxygen

Oxygen Free Copper Rods Chemical Composition :

1) Cu is determined by the difference between the impurity total and 100%. The Cu value is exclusive of Ag.
Note: This is a high conductivity copper which has, in the annealed condition a minimum concuctivity of 100% IACS except for Alloy C10100 which has a minimum conductivity of 101% IACS.
Note: The following additional impurity maximum limits shall apply: Bi, 1ppm (.0001%); Cd, 1ppm (.0001%); Fe, 10ppm (.0010%); Pb, 5ppm (.0005%); Mn, 0.5ppm (.00005%); Ni, 10ppm (.0010%); Se, 3ppm (.0003%); Ag, 25ppm(.0025%);S, 15ppm (.0015%); Sn, 2ppm (.0002%); Zn, 1ppm (.0001%).
