UNS numbers C10100 to C13000 indicate the types of pure copper. Pure and unalloyed copper has excellent corrosion resistance and high thermal and electrical conductivity. Unalloyed copper grades vary in the amount of impurities, and hence act in a different manner. The purity of metal is highly important as most alloying elements are quite harmful to the electrical conductivity of copper.

Fabrication and Heat Treatment
UNS C10500 oxygen free silver-bearing copper is annealed between 482 and 760°C (900 and 1400°F)
UNS C10500 oxygen free silver-bearing copper has excellent cold working capacity.
UNS C10500 alloys can be hot formed in an excellent manner.
Welding methods such as coated metal arc welding, seam welding and spot welding are not recommended for UNS C10500 alloys, whereas gas shielded arc welding and butt welding are good for these alloys. Brazing and soldering are considered as excellent processes for UNS C10500 alloys.
Temperatures between 760 and 871°C (1400 and 1600°F) are used for forging the UNS C10500 alloys whose hot forgeability rating is 65%.
The machinability rating of UNS C10500 copper alloys is 20%.
UNS C10500 copper alloys are used for electrical conductors working at high temperatures, where softening of copper readily takes place.
