Copper minerals have to be separated from the waste rock formations in which they are embedded before production of pure copper can begin.

It is a very impressive technological achievement to process rock with a few percent copper to a metal of For industrial applications, oxygen-free copper is valued more for its chemical purity than its electrical conductivity.

In practice the oxygen content is typically 0. OFHC is used for: The main bending magnets of the Large Thbe Collider are made from niobium-titanium conductors with a surrounding copper matrix and reach a maximum magnetic field of 8.

Impurities are removed by either combining with fluxes to form a slag which is removed, or by being oxidised to vapour by air oxygen. Of these tubf are widely used and two are considered oxygen-free. Oxygen-free copper OFC or oxygen-free high thermal conductivity OFHC copper is a group of wrought high conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to.

Magnetrons OFHC is used in specialist, powerful electronic equipment such as that used to generate microwaves. Properties In the annealed soft to hard condition the alloy has the following combination of properties:.


Ofhhc pitch copper is unsuitable for this application since it is less pure and might outgas c110000 high vacuum. Thus, they are widely used for heat exchangers, radiators, coolers, electro-heat-up pipe, air conditioner and refrigerators. Oxygen plays a beneficial role for improving copper conductivity. For equivalents of copper alloys worldwide, their chemical compositions, material designation and national standards.

All high conductivity coppers contain some oxygen as a result of the copper refining process but certain applications require copper with the highest purity and lowest oxygen levels, this is called Oxygen-free High Conductivity Copper OFHC. The excellent corrosion resistance was a major factor in the choice of OFHC for nuclear waste disposal canisters where the microstructure of the weld is particularly important, with no corrosion at all permitted in the very long life envisaged.

We maintains thbe of C OFE Copper in variety of shapes such as; sheet, plate, and round rod. Creep Creep is slow deformation of tuve material with time at temperature and must be allowed for in the design of any component operating above room temperature.

Oxygen-free copper – Wikipedia

CuOFP has been selected as corrosion resistant material for the overpack of spent nuclear fuel in the KBS-3 concept developed in Sweden and Finland to dispose high-level radioactive waste in crystalline rock formations. The Metallurgy of Copper Wire”. High Conductivity Copper for Electrical Engineering.

Oxygen-free phosphorus-containing copper CuOFP is typically used for structural and copler applications where the copper material will be subject to temperatures high enough to cause hydrogen embrittlement or more exactly steam embrittlement.


This section lists coppers and copper alloys for conductivity applications.

Alloy 101 OFE OFHC Copper Tube

Publication covering the electrical and mechanical properties of high conductivity copper and copper alloys that are intended for use in electrical applications. This process can cause the grains to be forced away from each other, and is known as steam embrittlement because steam is produced, not because exposure to steam causes the problem.

The purity of OFHC makes it suitable for conductivity applications in vacuum conditions. Copper Chemical Element Copper is a chemical element with the symbol Cu and atomic number Copper alloys which contain oxygen as an impurity in the form of residual oxides present in the metal matrix can be embrittled if exposed to hot hydrogen. Retrieved August 25, Furthermore, they are reliable in quality. The high-end speaker wire industry markets oxygen-free copper as having enhanced conductivity or other electrical properties that are supposedly advantageous to audio signal transmission.

High electrical conductivity coppers are distinct from coppers deoxidized by the addition of phosphorus in the smelting process. Views Read Edit View history. This copper does not suffer from steam hydrogen embrittlement when heated in a hydrogen reducing atmosphere.
