C11000 Copper Strip is a high-purity electrolytic tough pitch copper material known for its excellent electrical conductivity, thermal conductivity, and reliable processing performance. It provides an ideal balance of conductivity, formability, and cost efficiency for a wide range of electrical and industrial applications.
Widely used in electrical connectors, terminals, busbars, transformers, and precision stamped components requiring dependable conductivity and consistent performance.
C11000 copper strip (also referred to as ETP copper strip, Electrolytic Tough Pitch C11000 coil, or CDA 110 precision strip) is the standard high-conductivity pure copper strip used across electrical engineering, electronic packaging, and automotive component manufacturing. Containing a minimum copper purity of 99.90%, C11000 copper strips deliver exceptional electrical conductivity of at least 100% IACS, high thermal transfer efficiency, and reliable ductility.
At XQJ Metal, we produce high-precision C11000 copper strips in thin gauges, foil tempers, and heavy-duty spooled coil rolls. Manufactured in strict compliance with ASTM B152, ASTM B272, and EN 1652 standards, our ETP copper strip coils undergo continuous bright annealing to ensure mirror-smooth surface finish, tight slitting width tolerances, and uniform mechanical properties.

Q1: What is the main difference between C11000 and C10200 copper strips?
A: C11000 is Electrolytic Tough Pitch (ETP) copper containing small amounts of oxygen, making it extremely cost-effective for general electrical stamping and transformer windings. C10200 is Oxygen-Free Copper (OFC) with less than 0.001% oxygen, which is specifically required for vacuum applications or high-temperature welding in hydrogen environments.
Q2: What precision slitting tolerances can you achieve for C11000 copper strips?
A: With modern high-speed CNC slitting lines, we achieve width tolerances as tight as ±0.05mm and thickness tolerances within ±0.005mm depending on the gauge.
Q3: What is your Minimum Order Quantity (MOQ) for custom slit C11000 copper coils?
A: Our standard MOQ for custom slit strip dimensions is 200 kg. Standard warehouse coil widths can be dispatched in smaller trial batch quantities immediately.
