C11000 Copper Bar is a high-purity electrolytic tough pitch copper material known for its excellent electrical conductivity, thermal conductivity, and reliable mechanical performance. It offers an ideal balance of conductivity, workability, and cost efficiency for a wide range of industrial applications.
Widely used in electrical conductors, busbars, connectors, machined components, and industrial equipment requiring consistent performance and dependable conductivity.
C11000 copper bar (also known as ETP copper bar, Electrolytic Tough Pitch C11000 rod, or CDA 110 copper bar) is the most widely specified pure copper material for general electrical conductivity, thermal dissipation, and industrial fabrication. Containing a minimum copper purity of 99.90%, C11000 copper bar delivers an outstanding electrical conductivity rating of at least 100% IACS, high thermal conductivity, and dependable mechanical strength across a wide range of operating temperatures.
At XQJ Metal, we produce and export high-precision C11000 copper bars in round, square, rectangular busbar, and hexagonal profiles. Manufactured in full compliance with ASTM B187, ASTM B133, and EN 13601 standards, our ETP copper bars are produced through precision extrusion and cold drawing to ensure exact dimensional tolerances, sharp or rounded corners, and flawless surface finish.

Q1: What is the main difference between C11000 and C10200 copper bars?
A: C11000 is Electrolytic Tough Pitch (ETP) copper containing small controlled amounts of oxygen, making it cost-effective and ideal for standard electrical busbars. C10200 is Oxygen-Free Copper (OFC) with less than 0.001% oxygen, specifically required for vacuum devices or high-temperature welding in hydrogen environments where hydrogen embrittlement must be avoided.
Q2: Can C11000 copper bars be bent at 90 degrees without cracking?
A: Yes, in Half Hard (H02) or Soft Annealed (O60) tempers, C11000 copper busbars exhibit high ductility and can be cold bent 90 to 180 degrees cleanly without surface cracking.
Q3: What is your Minimum Order Quantity (MOQ) for custom C11000 copper profiles?
A: Our standard MOQ for custom extruded C11000 busbars is 300 kg. Standard warehouse dimensions can be shipped in smaller trial batches immediately.
