What is a C11000 copper pipe?

Copper alloy C11000, also known as electrolytic tough pitch (ETP) copper, is a commercially pure copper with high electrical conductivity and good thermal conductivity. It is characterized by its excellent ductility, formability, and corrosion resistance. C11000 copper is typically used in applications where electrical conductivity is paramount, such as electrical wiring, bus bars, conductors, and various electrical components. Its high purity and reliability make it a preferred material in electrical and electronic industries where efficient electrical transmission and heat dissipation are essential.
