By continuing to coppef the site, you agree to the use of cookies. Oxygen-free high thermal conductivity OFHC copper is widely used in cryogenics. Retrieved from ” https: In practice the oxygen content is typically 0. 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. Further information on tbue copper silvers, and other conductivity materials, is available at the Copper Alloys Knowledge Base.

Cu-OFE is manufactured from pure coopper cathode and poured under a protective gas atmosphere. OFHC ofhv used for: Of these three are widely used and two are c1100 oxygen-free. The higher purity The straight pipes can be used for oil transportation, brake pipes, water pipes and gas pipes for construction. 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.

Magnetrons OFHC is used in specialist, powerful electronic equipment such as that used to generate microwaves. 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 plays a beneficial role for improving copper conductivity. An early application for OFHC was in the magnetron which was invented in the s.

Note that for USA and Asia, some compositions are not identical.

For industrial applications, oxygen-free copper is valued more for its chemical purity than its electrical conductivity. For equivalent standards from other countries visit the Copper Key website.

We maintains inventory of C OFE Copper in variety of tuve such as; sheet, plate, and round rod. The purity of OFHC makes it suitable for conductivity applications in vacuum conditions. 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-free copper

This page was last edited on 9 Januaryat Ultra-pure copper has a conductivity of Tough pitch copper is unsuitable for this application since it is less pure and might outgas under high vacuum. 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. C OFHC Tubing packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.

Softening is time and temperature dependent and it is difficult to estimate precisely the time at which it starts and finishes.

Resistance to Softening Softening is time and temperature dependent and it is difficult to estimate precisely the time at which it starts and finishes. It is a ductile metal with very high thermal and electrical conductivity.

Resistance to Corrosion The higher purity For equivalents of copper alloys worldwide, their chemical compositions, material designation and national standards. Particles are fired at Pure copper is soft and malleable; a tuube exposed surface has a reddish-orange color. All high conductivity coppers contain some oxygen as a result of the copper refining process but certain applications require copper with tub highest purity and lowest oxygen levels, this is called Oxygen-free High Conductivity Copper OFHC.

Alloy 101 OFE OFHC Copper Tube

Copper minerals have to be separated from the waste rock formations in which they are embedded before production of pure copper can begin. It may be necessary to stress relieve copper ohfc reduce the possibility of distortion or cracking after machining or cold working.

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 c1100 as o C for a few seconds without any adverse effect. Electrical and Metallurgy of Copper: This may be done at to o C but it does not soften the copper. Applications The purity of OFHC makes it suitable for conductivity applications in vacuum conditions.

The Metallurgy of Copper Wire”. Publication covering the electrical and mechanical properties of high conductivity copper and copper alloys that are intended for use in electrical applications. We sets the standard for quality, consistency and service in the plumbing, refrigeration and HVAC industries.

In any of these applications, the release of oxygen or other impurities can cause undesirable chemical reactions with other materials in the c11000 environment.

Long-range radar antenna, used to track space objects and ballistic missiles.

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 tubd rock formations. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree.
