C11000 OFHC COPPER TUBE PDF

Copper is widely viewed as a barometer for the health of the overall global economy since it is used in electronics, homes and infrastructure. Copper Alloys have excellent electrical and thermal conductivity. This alloy is also used in the distillery kettle vats, pressure vessels and other such like process equipment. Its resistance to corrosion enables longevity. Copper sheet has been used in the construction roofing industry for over years. Copper has a unique decorative appearance with its aesthetically pleasing green patina hue that forms over time.

Fenris Individual alloy ovhc include details of specifications, mechanical and physical properties, available product forms and applications. In any of these applications, the release of oxygen or other impurities can cause undesirable chemical reactions with other materials in the local environment.

High Conductivity Copper for Electrical Engineering. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. The method of producing OFHC c ensures extra high grade of metal with a copper content of For equivalents of copper alloys worldwide, their chemical tuhe, material designation and national standards.

Microwaves are made by a magnetron which at its 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. Oxygen plays a beneficial role for improving copper conductivity. Coppper is where the oxygen in air plays an important part. For industrial applications, oxygen-free copper is valued more for its chemical purity than its electrical conductivity.

The microwaves are channelled by an OFHC waveguide, either into the cooking compartment of a microwave oven or beamed out into the air by an antenna or satellite dish in radar equipment. 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.

For equivalent kfhc from other countries visit the Copper Key website. Applications The purity of OFHC makes it suitable for conductivity applications in vacuum conditions. Copper minerals have to be separated from the waste rock formations in which they are embedded before production of pure copper can begin. Properties In the annealed soft c hard condition the alloy has the following combination of properties:. Sulphur has an adverse effect on the creep resistance of copper: Quick Facts Properties In the annealed soft to hard condition the alloy has the following combination of properties: It may be necessary to stress relieve copper to reduce the possibility of distortion or cracking after machining or cold working.

Of these three are widely used and two are considered oxygen-free. Publication covering the electrical and mechanical properties of high conductivity copper and copper alloys that are intended for use in electrical applications.

Further information on oxygen-free copper silvers, and other conductivity materials, is tibe at the Copper Alloys Knowledge Base. This section lists coppers and copper alloys for conductivity applications. Oxygen-free phosphorus-containing copper CuOFP is typically used for structural and thermal applications where the copper material will be subject to temperatures high enough to cause hydrogen embrittlement or more exactly steam embrittlement.

The purity of OFHC makes dopper suitable for conductivity applications in vacuum conditions. Oxygen-free copper — Wikipedia Impurities are removed by either combining with fluxes to form a slag which is removed, or by being oxidised to vapour by air oxygen. Heat Treatment It may be necessary to stress relieve copper to reduce the possibility of distortion or cracking after machining or cold working.

C copper is produced by melting and pouring copper in the presence of carbon or carbonaceous gases so the oxygen can be absorbed. This page was last edited on 9 Januaryat An early application for OFHC was in the magnetron which was invented in the s. C OFHC Tubing packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage. 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.

We welcome your quries and happy to club you in our list to provide you with the best service of Multimet Overseas. Microwaves are the invisible, super-energetic, short wavelength radio waves that travel at the speed of light used in microwave ovens and radar radio detection and ranging navigation equipment. This is the highest conductivity of all the coppers. There are advanced refining ofjc such as the Czochralski process than can be used to reduce impurity levels to below the C specification by reducing copper grain density.

During the copper smelting process, oxygen is deliberately injected into the melt to scavenge impurities ccopper would otherwise degrade conductivity. Oxygen-free high thermal conductivity OFHC copper is widely used in cryogenics. The high-end speaker wire industry markets oxygen-free copper as having enhanced coppe 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.

From Wikipedia, the free encyclopedia. Besides, they are of good heat conductibility. It is a very impressive technological achievement to process rock with a few percent copper to a metal of It is the purest grade of any of the coppers. Note that for USA and Asia, some compositions are not identical. Related Posts.

This copper does not suffer from steam hydrogen embrittlement when heated in a hydrogen reducing atmosphere. Views Read Edit View history. OFHC is used for:. Resistance to Corrosion The higher purity Creep is slow ofhd of a material with time at temperature and must be allowed for in the design of any component operating above room temperature. For equivalents of copper alloys worldwide, their chemical compositions, material designation and national standards. Microwaves are the invisible, super-energetic, short wavelength radio waves that travel at the speed of light used in microwave ovens and radar radio detection and ranging navigation equipment.
