C11000 Copper Bar is an electrolytic tough pitch copper bar complying with ASTM standards, with a minimum copper content of 99.90%. It provides excellent electrical and thermal conductivity, good mechanical strength, and superior formability. It features high ductility, stable performance, and good corrosion resistance in atmospheric environments. The bar has uniform structure, precise dimensions, and smooth surface, making it easy to machine, drill, and process. Widely used for its reliability and cost-effectiveness, it is the most common pure copper bar for general industrial and electrical applications.
