Copper Round Bar, is widely known for its electrical applications whereas it has very high electrical and thermal conductivity. In addition, copper round bars are used in artistic works along with architectural applications because of its corrosion resistance and familiar green patina appearance acheived after being exposed to the elements. Copper rounds have excellent hot or cold workability and is very ductile when heated.
