Pure coppers are designated as UNS C10100 to C13000. Pure and unalloyed coppers have high corrosion resistance, and good electrical and thermal conductivity. Impurities present in different grades of unalloyed copper are different from each other. UNS C10200 Oxygen free coppers are mainly applied in most of the applications that require high ductility and conductivity.
