C11000 Copper Sheet is a high-purity electrolytic tough pitch copper material known for its excellent electrical conductivity, thermal conductivity, and reliable fabrication performance. It offers an ideal balance of conductivity, workability, and cost efficiency for a wide range of electrical and industrial applications.
Widely used in electrical equipment, power distribution components, heat transfer systems, and industrial fabrication projects requiring dependable conductivity and consistent performance.
C11000 copper sheet (also known as ETP copper sheet, Electrolytic Tough Pitch C11000 plate, or CDA 110 copper strip) is the most widely specified pure copper sheet material for general electrical conductivity, thermal dissipation, and industrial metal fabrication. Containing a minimum copper purity of 99.90%, C11000 copper sheets deliver an excellent electrical conductivity rating of at least 100% IACS, high thermal conductivity, and reliable mechanical performance.
At XQJ Metal, we manufacture and supply high-precision C11000 copper sheets, plates, and coils in a wide range of thicknesses and tempers. Produced in strict compliance with ASTM B152, ASTM B272, and EN 1652 standards, our ETP copper sheets are available with custom precision shearing, CNC laser cutting, edge deburring, and protective film interleaving.

Q1: What is the main difference between C11000 and C10200 copper sheets?
A: C11000 is Electrolytic Tough Pitch (ETP) copper with small amounts of oxygen, making it highly cost-effective for general electrical, architectural, and thermal applications. C10200 is Oxygen-Free Copper (OFC) with less than 0.001% oxygen, which is required for vacuum devices or high-temperature brazing in reducing hydrogen atmospheres to prevent hydrogen embrittlement.
Q2: Can C11000 copper sheets be cold bent or deep drawn?
A: Yes, in Soft Annealed (O60) or Half Hard (H02) tempers, C11000 copper sheet exhibits superior ductility, allowing smooth cold bending, stamping, and deep drawing without cracking.
Q3: What is your Minimum Order Quantity (MOQ) for custom sheared C11000 sheets?
A: Our standard MOQ for custom cut-to-size C11000 sheets is 300 kg. Standard warehouse sizes can be dispatched in smaller trial quantities immediately.
