QIDAMT · COPPER COIL

C11000 Copper Coil – ETP Pure Copper Strip & Bobina

Electrolytic tough pitch (ETP) copper coil with 101% IACS conductivity for electrical, thermal and stamping applications.

C11000 copper coil is produced from electrolytic tough pitch copper with a minimum copper content of 99.90%. It combines the highest practical electrical conductivity with excellent formability, making it the default material for busbars, transformer windings, cable shielding, radiators and precision stamped parts.
