Oxygen free copper products
Do you need oxygen free copper for your application ?
Do you need copper products for use in a vacuum or cryogenic application ?
Oxygen-free high thermal conductivity (OFHC) copper is widely used in cryogenics. OFHC 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 insures 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 are high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low relative volatility under high vacuum.
We supply a range of oxygen free copper for use in scientific, industrial and medical processes. Our customers include the Accelerator Science and Technology Centre, Daresbury Laboratory, Warrington - Cavendish Laboratory, Cambridge - Imperial College, London - Sussex Univeristy, Brighton - Cardiff Univeristy, Wales - CIEMAT, Madrid, Spain - Lawrence Berkley National Laboratory, California - University of British Columbia, Canada.
Copper alloy 10100 oxygen free copper, also known in Europe as Cu-OF or CW008A to EN13601.
Composition: Copper 99.99 %, Trellium 0.001 %
Hardness: B30 - 40
Conductivity: 101 %
Tensile strength: 25 - 40 Ksi
In simple terms the thermal conductivity of pure copper is about 400 watts per meter kelvin. This means that a plate of copper with area A and thickness L whose faces are kept at a constant relative temperature difference of deltaT Kelvin will conduct heat at a rate of 400.A/L.deltaT joules per second.
