Oxygen Free Copper (Cu-Of) 1

[cillo]

Does anybody Know why Oxygen Free Copper Re-Draw Rod has very good characteristics in enamelled wire applications, data trasmission. Any new about this matter is in my interest. Thank'you [sig][/sig]

I think that it has something to do with reducing the corrosion potential in the copper. Without the oxygen it does not corrode in the environment as easily. I used this material before in clean room vacuum pump seals. They had to be oxygen free copper. I am not completely certain, but that is all I remember. The name is kind of a misnomer, it is not that it does not have oxygen, but that it is smelted in a oxygen free evvironment.

From what I understand it's more of a resistance feature.
O2 free copper has less resistance so can take a higher electrical load with less heating effect.

magnetchief is correct. You can find a great deal of information on copper alloys at the copper.org website.

One thing not mentioned is the OFHC or just OF is a lot more malleable than most other coppers, therefore the wire won't break the insulation on bending.

We used nickel plated OFHC as a gasket material in several high pressure systems and a quick test was to bend it back on itself and see if cracked.
