The method of producing OFHC copper ensures extra high grade of metal with a copper content of Properties A summary of the properties is shown from the annealed soft condition to hard. 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. Of these three are widely used and two are considered oxygen-free.

This page was last edited on 9 Januaryat There are two grades: The hydrogen diffuses through the copper and reacts with inclusions of Cu 2 Oforming H 2 O waterwhich then forms pressurized water steam bubbles at the grain boundaries. Being prominent manufacturer and exporter of a broad array of C OFHC Tubing, we offer C OFHC Tubing that are fabricated by our adroit professionals using supreme class raw materials as per the set industry norms. For equivalents of copper alloys worldwide, their chemical compositions, material designation and national standards.

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

There are advanced refining processes such as the Czochralski process than can be ofhhc to reduce impurity levels to below the C specification by reducing copper grain density. We welcome your quries and happy to club you in our list to provide you with the best service of Multimet Overseas. Further information on oxygen-free cppper silvers, and other conductivity materials, is available at the Copper Alloys Knowledge Base.

Particles are fired at The copper tubes ofgc made of pure electrolysis copper. The historical significance of the magnetron is that it allowed the development of radar and its use in defence in planes, ships and submarines in the s. If this is required then a full anneal at to o C is needed. The alloys are grouped by property.

C Copper – ETP C Copper | Farmers Copper

It has been established tkbe that such copper would operate successfully at a temperature of o C for periods of years, and that it could withstand short-circuit conditions as high as o C for a few seconds without any adverse effect. Long-range radar antenna, used to track space objects and ballistic missiles.

Microwave tubes Vacuum capacitors Vacuum interrupters Vacuum seals Vacuum tubes for radio and TV transmitters, klystrons and magnetrons Waveguides Available Forms OFHC is available in bar, plate, profiles, rod, sheet, strip, tube and wire. The higher purity Magnetrons OFHC is used in specialist, coppper electronic equipment such as that used to generate microwaves.

Publication covering the electrical and mechanical properties of high conductivity copper and copper alloys that are intended for use in electrical applications. The main bending magnets of the Large Hadron Collider are made from niobium-titanium conductors with a surrounding copper matrix and reach a maximum magnetic field of 8. OFHC is used for:. Views Read Edit View history. Retrieved from ” https: 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 coppper.

Cu-OFE is manufactured from pure copper cathode and poured under a protective gas atmosphere. Resistance to Softening Softening is time and temperature dependent and it is difficult to estimate precisely the time at which it starts and finishes. OFHC is used in specialist, powerful electronic equipment such as that used to generate microwaves. Copper minerals have to be separated from the waste rock formations in which they are embedded before production of pure copper can begin.


OFHC is used for: In oxygen-free high conductivity copper, all traces of oxygen are removed by either melting in a vacuum, using an inert atmosphere coppet a reducing environment resulting in a very pure In any of these applications, the release of oxygen or other impurities can cause undesirable chemical reactions with other materials in the local environment. 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.

This copper does not suffer from steam hydrogen embrittlement when heated in a hydrogen reducing atmosphere.

The straight pipes can be used for oil transportation, brake pipes, water pipes and gas pipes for construction. This is the highest conductivity of all the coppers.

This is because it is a single phase structure with no second phases impurities present which might form tiny galvanic cells and cause galvanic corrosion. Copper cannot be hardened by heat treatment. During the copper smelting process, oxygen is deliberately injected into the melt to scavenge impurities that would otherwise degrade conductivity.

Furthermore, they are oghc in quality.

The copper minerals are separated from the waste rock then crushed to a fine powder and melted in a furnace. Oxygen plays a beneficial role for improving copper conductivity.

High electrical conductivity coppers are distinct from coppers deoxidized by the addition of phosphorus in the smelting process.

Impurities are removed by either combining with fluxes to form a slag which is removed, or by being oxidised to vapour by air oxygen. 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.

This may be done at to o C but it does not soften the copper.
