Atlas carries C10100 Oxygen Free High Conductivity Copper (OFHC) in Sheet / Plate, Rod & Tubing. We carry a very large range of sizes and will cut the material to length.
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

(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%).
