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. 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. It is a ductile metal with very high thermal and electrical conductivity.

OFHC is used for:. Thus, they are widely used for heat exchangers, radiators, coolers, electro-heat-up pipe, air conditioner and refrigerators. 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.

Oxygen-free High Conductivity Copper

This page was last edited on 9 Januaryat 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. Resistance to Corrosion The higher purity Of these three are widely used and two are considered oxygen-free. There are advanced refining processes such as the Czochralski process than can be used to reduce impurity levels to below the C specification by reducing copper grain density.

Magnetrons are used to produce microwaves in microwave ovens. For coppfr applications, oxygen-free copper is valued more coppee its chemical purity than its electrical conductivity.

It is a very impressive technological achievement to process rock with a few percent copper to a metal of This section lists coppers and copper alloys for conductivity applications. 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.


This is where the oxygen in air plays an important part. 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. Microwaves are made by a magnetron which at dopper heart has a ring shaped OFHC copper cathode which vibrates and emits microwaves when excited by a stream of electrons emitted in a vacuum from an anode.

C10100 OFHC Tubing manufacturer

Being prominent manufacturer and exporter of a broad array of C OFHC Tubing, we offer C OFHC Tubing that coppdr fabricated by our adroit professionals using supreme class raw materials as per the set industry norms.

Quick Facts Properties In the annealed soft to hard condition the alloy has the following combination of properties: The straight pipes can be used for oil transportation, brake pipes, water pipes and gas pipes for construction.

Ultra-pure copper has a conductivity of Long-range radar antenna, used to track space objects and ballistic missiles. Impurities are removed by either combining with fluxes to form a slag which is removed, or by being oxidised to vapour by air oxygen.

Views Read Edit View history. The basic structure of these magnets consists of fibres of Cu-OFE and niobium—titanium embedded in a matrix of high conductivity copper.

The high conductivity, high purity and low volatility under high vacuum make OFHC ideal for use in a magnetron because it is not subject to outgassing release of trapped gas such as oxygen. It has been established experimentally 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. The high conductivity, high purity and low volatility under high vacuum make c1100 ideal for this use because it is not subject to outgassing release of trapped gas such as oxygen.


It may be necessary to stress relieve copper to reduce the possibility of distortion or cracking after machining or cold working. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree. Creep Creep is slow deformation of a material with time at temperature and must be allowed for in the design of any component operating above room xopper.

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 c1100 that are supposedly advantageous to audio signal transmission. Copper cannot be hardened by heat treatment. We welcome your quries and happy to club copler in our list to provide you with the best service of Multimet Overseas.

These characteristics are high ductilityhigh electrical and thermal conductivityhigh impact strengthgood creep resistance, ease of weldingand low relative volatility under high vacuum. Further information on oxygen-free copper silvers, and other conductivity materials, is available at the Copper Alloys Knowledge Base.

The main bending magnets of the Coppef Hadron Collider are made from niobium-titanium conductors with a surrounding copper matrix and reach a maximum magnetic field of 8. The copper tubes are utbe of pure electrolysis copper.
