CuOFE (CuOF1 - EN: CR007A, CW007A, UNS: C10200 and CuOF - EN: CR008A, CW008A, UNS: C10200) is a high purity, oxygen free, non-phosphorus-deoxidized copperthat does not contain in vacuum evaporating elements.

Applications

Main applications

The assortment of oxygen free copper products is very broad and is concentrated mainly on highly advanced products. Oxygen free copper of the highest quality is mainlyused in electron technology (accelerator elements and electron tubes), vacuum apparatus, cryogenics (elements operating at low temperatures), superconduction, cabletechnology (connecting elements, microwires, enamelled conductors, transmission conductors, conductors for applications in information technology, audio-videoconductors). Interest in the dynamically developing oxygen free copper electro-technical industry, its production technology, as well as its physical and mechanicalproperties, is a result of the wide applications of this material. One application of oxygen free copper is the production of wires and microwires with diameters of less than0.1 mm. Such capacity for use of oxygen free copper in the drawing process is related to the limited potential of the traditionally used ETP grade copper for electricapplications, characterized by its content of hard copper oxides (Cu2O) with sizes of 5÷10 µm, which, for very small wire diameters, significantly decrease their ductility.

It is the chemical purity of copper that is the guarantor and fundamental requirement for obtaining high electric conductivity of the material. Moreover typical uses ofoxygen free copper are busbars, waveguides, lead-in wire, anodes, vacuum seals, transistor components, glass-to-metal seals, coaxial cables, klystrons, microwave tubes.Heating in oxidizing atmospheres at high temperatures should be avoided because of the danger of oxidation.
