QIDAMT · COPPER COIL

C11000 Copper Coil – ETP Pure Copper Strip & Coil

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.

Key Advantages

Highest practical conductivity for electrical parts.

Excellent Formability

Deep drawing, bending and stamping friendly.

High Ductility

Soft temper allows elongation above 35%.

Weldable & Brazable

Good response to soldering and brazing.
