CuOFE
EN: CR009A, CW009AUNS: C10100
MANUFACTURERS LIST
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. It has a very high electrical and thermal conductivity, good welding and excellent soldering properties. It has excellent hotand cold forming properties, and a good corrosion resistance, especially in atmosphere due to a good adherence of the oxide layer. CuOF can be heat treated in reducingatmosphere. Characteristics are high ductility, high impact strength, good creep resistance and low relative volatility under high vacuum. The alloy is registered US EPAantimicrobial. The lack of oxygen in oxygen free copper is the main reason for the improvement of its plasticity, electric conductivity, resistance to corrosion and resistance tohydrogen embrittlement relative to ETP copper. Oxygen content below 5 ppm makes it impossible for copper oxides, CuO and Cu2O, which hinder the process of drawing
wires with diameters of less than 0.1 mm, to form. Furthermore, the presence of copper oxides leads to a decrease in corrosion resistance and makes heat treatment in ahydrogen atmosphere impossible (hydrogen embrittlement). Copper is cathodic to hydrogen in the electromotive series and therefore is the cathode in galvanic couples withother base metals such as iron, aluminium, magnesium, lead, tin and zinc. C10100 and C10200 have excellent resistance to atmospheric corrosion and to corrosion by mostwaters, including brackish water and seawater. They have good resistance to nonoxidizing acids but poor resistance to oxidizing acids, moist ammonia, moist halogens, sulfides,and solutions containing ammonium ions. CuOFE is produced by the direct conversion of selected refined cathodes and castings under carefully controlled conditions to preventcontamination 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.

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.
