Forging conditions
Rough pieces are obtained by heat forging at a convenient temperature to obtain required metallurgical, physical and mechanical characteristics, as per each customer' requirements… In any case, please contact us.
Properties / Main use conditions
CuC (Cu-OF and Cu-OFE) coppers are characterized by their highest purity, and by absence of residual deoxidizing. They are obtained by electrolitic way, and are remelt in reducing atmospheres, American type process (OFHC), or with controlled addition of non-residual deoxidizers, German type process (NA class BE58). These coppers have the same advantages as all other categories (Cu-a and Cu-b) with highest electrical and thermal conductivity, and a best capacity for welding. Cu-C2 class having a better purity and limited oxygen value (inferior to 5 ppm) is more convenient for application requiring a high vacuum.
Main applications
All pieces having to be used in high vacuum, and requiring high electrical and thermal characteristics, or able to be fitted by welding or brazing : radar tubes, electronical tubes, high power laser ranging retro-reflector particule accelerators.
