Products Description
ASTM B111 C10100 Oxygen-Free Electronic Copper (OFE) is a 99.99 percent pure copper with only 0.0005% oxygen concentration. C10100 OFHC Copper Pipes are made by directly converting selected refined cathodes and castings under carefully regulated circumstances to ensure that the pure oxygen-free metal is not contaminated during manufacturing. OFHC copper is produced in such a way that it is of very high quality, with a copper concentration of 99.99 percent. The intrinsic qualities of elemental copper are brought forward to a great degree with such a low amount of extraneous elements.
Unalloyed copper, often known as oxygen-free copper, has excellent corrosion resistance as well as excellent thermal and electrical qualities. These oxygen-free coppers are ideal for applications requiring good conductivity and ductility. Under high vacuum, C10100 OFE possesses excellent ductility, strong electrical and thermal conductivity, and low volatility.
Copper UNS C10100 Tubes are used for a variety of applications, including electrical and electronic conductors, High Resistance-Ratio Cryogenic Shunts, Bus Conductors, Hollow Conductors, Anodes for Vacuum Tubes, Coaxial Tube, Microwave Tubes, Waveguides, Cavity resonators, Superconductor matrixes, Vacuum tube, and solid-state devices, and Glass-to-metal seals, among others.
