Copper Cuc1 or Cu OF : Oxygen-free electrolytic copper
Copper Cu OF (Oxygen Free) is a high purity copper without oxygen. This copper, also known as Cuc1, has a high electrical conductivity. It is characterised above all by its minimum copper content of 99.95%. With such a high copper content in its composition, it is insensitive to reducing atmospheres. Thanks to its very low impurity content, it is ideal for use in the electronics industry. This copper has all the qualities of the other categories (Cu-a and Cu-b) but with greater electrical and thermal conductivity and better solderability.
Cu OF and its standards
Cu OF has other international designations such as :
- France (AFNOR): CuC1/ Cu-OF
- Germany (DIN): OF-Cu
- Europe (EN): CW008A
- ASTM : C10200
