What Is Oxygen-Free Copper? - IMS

2021610 · By IMS Team June 10, 2021. Oxygen-free copper (OFC) describes a group of high-conductivity copper alloys that are electrolytically refined to reduce the oxygen level to 0.1% or lower. These copper alloys are often used in industrial electronics applications because of their high conductivity, chemical purity, and high ductility.

Oxygen Free Copper (Alloy 101/C10100) - Sequoia Brass

The two basic grades are: Cu-OF (C10200) grade copper is oxygen-free up to 99.95%. This grade of copper boasts exceptional purity. While no copper is ever 100% pure, modern technology has allowed refiners to reduce the remaining oxygen content to a practical range of 0.001–0.003%. Cu-OFE (C10100) grade copper is oxygen-free up to 99.99%.

What Distinguishes Pure Copper vs. Oxygen-Free Copper

2022628 · Oxygen-free copper has: A rich conductivity profile. High immunity to hydrogen embrittlement. Superior cryogenic properties. Excellent malleability. Oxygen-free copper is available in the following three grades: C10100 (OFE): 99.99% pure copper with 0.0005% oxygen content. C10200 (OF): 99.95% pure copper with 0.001% oxygen content.

What is oxygen free copper used for? | WIHO Industrial

Oxygen-free copper is a type of pure copper alloy which are highly refined to less than 0.5% oxygen concentration. In this state, the alloys retain their metallic properties but are free of oxygen and all pure copper alloys in an unoxidized (oxygen-free) form. Pure copper is highly reactive with moisture, making it unusable as an electrode in ...

What is the chemical formula of copper (ii)

The grade is known in the copper wire industry as ETP Copper, This si a high purity grade of copper (Cu) melted with an addition of oxygen controlled at 100–450 ppm, so the chemical composition ( formula) is Cu, O with Cu at 99.9% min, O at 100–450ppm. Note: oxygen is added to oxidize impurities and maximize electrical conductivity.

Why is copper a better conductor than other

ETP copper contains a small percentage of oxygen (0.02 to 0.04%). If high conductivity copper needs to be welded or brazed or used in a reducing atmosphere, then oxygen-free copper may be used.

201988 · If you would like to construct a half-wave dipole, at 20 Hz it would be about 2000 miles long. As for OFC (oxygen-free copper) vs. CCA (copper-clad aluminum), there are plenty of measurements showing the difference. CCA uses a thin layer of copper over an Al core and thus has much higher resistance than pure copper.
