C11000 Copper Sheet, also known as C110 ETP (Electrolytic Tough Pitch) Copper, contains a minimum of 99.90% copper. Its high electrical and thermal conductivity makes it a standard choice for power distribution equipment, electrical components, and industrial fabrication.
Typical applications include busbars, switchgear parts, electrical terminals, connectors, and conductive plates. C11000 can be cut, bent, stamped, and punched to produce components with different shapes and dimensions. It also has good solderability for electrical connections and assemblies.
Compared with oxygen-free copper grades such as C10100 and C10200, C11000 is often a more economical option for general electrical applications. However, its oxygen content makes it susceptible to hydrogen embrittlement when heated in hydrogen-containing reducing atmospheres. Oxygen-free copper is generally preferred for high-temperature brazing or annealing under these conditions.
Sky Steel Group supplies C11000 copper sheets to electrical equipment manufacturers, metal fabricators, and industrial distributors. Sheets can be supplied in different thicknesses and dimensions, with cut-to-size processing available according to customer drawings and order requirements.

Frequently Asked Questions About C11000 Copper Sheet (C110 ETP Copper)
1. What is C11000 copper sheet?
C11000 is Electrolytic Tough Pitch (ETP) copper containing at least 99.90% copper. It provides approximately 100% IACS electrical conductivity in the annealed condition and is widely used for busbars, switchgear, power distribution equipment, and electrical components.
2. What is the difference between C11000 and C10100 copper?
C11000 is ETP copper containing a small amount of oxygen, while C10100 is Oxygen-Free Electronic (OFE) copper with a minimum purity of 99.99%. C11000 is generally more economical for standard electrical applications. C10100 is preferred for applications requiring very low oxygen content, particularly high-temperature processing in reducing atmospheres where hydrogen embrittlement is a concern.
3. What are the main applications of C11000 copper sheet?
Typical applications include electrical busbars, switchgear components, power distribution panels, terminals, connectors, architectural cladding, and heat transfer equipment.
4. Can C11000 copper sheet be bent, stamped, or welded?
Yes. C11000 can be bent, stamped, punched, and soldered. Soft annealed (O60) copper is better suited to tight-radius bending, while half-hard (H02) provides higher strength and stiffness. Welding and brazing require suitable procedures, especially at elevated temperatures in hydrogen-containing reducing atmospheres.
5. What thicknesses and sizes are available for C11000 copper sheet?
Sky Steel Group supplies C11000 copper sheets in standard and custom dimensions. Cut-to-size processing is available according to project requirements. Please provide the required thickness, width, length, temper, and order quantity for confirmation.
6. What standards and certificates are available for C11000 copper sheet?
C11000 copper sheet is commonly specified to ASTM B152/B152M. Mill Test Certificates (MTC) are available upon request. If EN 10204 3.1 inspection documentation or specific test results are required, please confirm these requirements before placing an order.
