Products Description
Unalloyed copper or oxygen free coppers have good corrosion resistance and high thermal and electrical properties. Unalloyed coppers of different grades vary based on the amount of impurities present, and have different characteristics. UNS designations of commercially available pure copper are C10100 to C13000. These oxygen free coppers are suitable for applications, which require ductility and high conductivity.
