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.
This is where the oxygen in air plays an important part. Quick Facts Properties In the annealed soft to hard condition the alloy has the following combination of properties: OFHC is used for: This may be done at to o C but it does not soften the copper.
Sulphur has an adverse effect on the creep resistance of copper: It is the purest grade of any of the coppers. This copper does not suffer from steam hydrogen embrittlement when heated in a hydrogen reducing atmosphere. Views Read Edit View history. The purity of OFHC makes it suitable for conductivity applications in vacuum conditions. Retrieved 21 May High electrical conductivity coppers are distinct from coppers deoxidized by the addition of phosphorus in the smelting process.
Oxygen-free copper – Wikipedia
Long-range radar antenna, used to track space objects and ballistic missiles. Publication covering the electrical and mechanical properties of high conductivity copper ofhv copper alloys that are intended for use in electrical applications. 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 temperature.
There are two grades: They are precise in size and smooth on surface. Tough pitch copper is unsuitable for this application since it is less pure and might outgas under high vacuum. The alloys are xopper by property. Ultra-pure copper has a conductivity of Further information on oxygen-free copper silvers, and other conductivity materials, is available at the Copper Alloys Knowledge Base.
We welcome your quries and happy to club you in our list to provide you with the best service of Multimet Overseas. Note that for USA and Asia, some compositions are not identical. OFHC is used in specialist, powerful electronic equipment such as that used to generate microwaves.
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 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. The method of producing OFHC copper ensures extra high grade of metal with a copper content of For equivalent standards from other countries visit the Coppre Key website.
Oxygen-free high thermal conductivity OFHC copper is widely used in cryogenics. This is the highest conductivity of all the coppers. The high conductivity, high purity and low volatility under high vacuum make it ideal for this use because it is not subject to outgassing release of trapped gas such as oxygen.
Thus, they are widely used for heat exchangers, radiators, coolers, electro-heat-up pipe, air conditioner and refrigerators. 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. 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 magnets keep the particles on their orbit around the machine and focus the beams. The straight pipes can be used for oil transportation, brake pipes, water pipes and gas pipes for construction.
Oxygen-free High Conductivity Copper for electrical applications
C copper is produced by melting and pouring copper in the presence of carbon or carbonaceous gases so the oxygen can be absorbed. It may be necessary to stress relieve copper to reduce the possibility of distortion or cracking after machining or cold working. Impurities are removed by either combining with fluxes to form a slag which is removed, or by being oxidised to vapour by air oxygen.
These characteristics are high ductilityhigh electrical and thermal conductivityhigh impact strengthgood creep resistance, ease of weldingand low relative volatility under high vacuum.
