Pure copper has high electrical and thermal conductivity due to its alloying metals. The UNS numbers C10100 to C13000 denote commercially pure copper. Pure copper is corrosion resistant and exceptionally ductile. Different grades of unalloyed copper perform differently owing to the amount of impurities present in it.
