Resistance to Corrosion The higher purity The magnets keep the particles on their orbit around the machine and focus the beams. We maintains inventory of C OFE Copper in variety of shapes such as; sheet, plate, and round rod. This process can cause the grains to be forced away from each other, and is known as steam embrittlement because steam is produced, not because exposure to steam causes the problem.

High electrical conductivity coppers are distinct from coppers deoxidized by the addition of phosphorus in the smelting process. C copper is produced by melting and pouring copper in the presence of carbon or carbonaceous gases so the oxygen can be absorbed.

From Wikipedia, the free encyclopedia. The coppper pipes can be used for oil transportation, brake pipes, water pipes and gas pipes for construction.

OFHC is used for:. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree. UK Standards are superseded by European Standards.

Note that for Ifhc and Asia, some compositions are not identical. There are two grades: C OFHC Tubing packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.

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. 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.

Tough pitch copper is unsuitable for this application since it is less ocpper and might outgas under high vacuum. Softening is time and temperature dependent and it is difficult to estimate precisely the time at which it starts and finishes.

The alloys are grouped by property.

Alloy 101 OFE OFHC Copper Tube

During the copper smelting process, oxygen is deliberately injected into the melt to scavenge impurities that would otherwise degrade conductivity. Applications The purity of OFHC makes it suitable for conductivity applications in vacuum conditions. This may be done at to o C but it does not soften the copper. Retrieved from ” https: The copper minerals are separated from the waste rock then crushed to a fine powder and melted in a furnace.

For equivalents of copper alloys worldwide, their chemical compositions, material designation and national standards. 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.

These characteristics are high ductilityhigh electrical and thermal conductivityhigh impact strengthgood creep resistance, ease of weldingand low relative volatility under high vacuum. 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 minerals have to be separated from the waste rock formations in which they are embedded before production of pure copper can begin. 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. 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.


This copper does not suffer from steam hydrogen embrittlement when heated in a hydrogen reducing atmosphere. The Metallurgy of Copper Wire”. If this is required then a full anneal at to o C is needed. 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.

The higher purity Cu-OFE is manufactured from pure copper cathode and poured under a protective gas atmosphere. Heat Treatment It may be necessary to stress relieve copper to d11000 the possibility of distortion or cracking after machining or cold working. Oxygen-free high thermal coppe OFHC copper is widely used in cryogenics.

Resistance to Softening Softening is time and temperature dependent and it is difficult to estimate precisely the time at which it starts and finishes. 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. Magnetrons OFHC is used in specialist, powerful electronic equipment such as that used to generate microwaves.
