Copper-Zirconium (C15000)

Class 1

Only trace amounts of zirconium need be added to create this alloy that has only .2% Zirconium. By adding it, the copper is made much stronger and thermal conductive.

Something that distinguishes this alloy is the fact that it is used to weld galvanized materials because of its great thermal conductivity. It has been designated by the RWMA as a class 1 copper.
