High Purity C11000 Electrolytic Tough Pitch (ETP) Copper Plate Excellent Electrical Conductivity and Formability

High Purity C11000 Electrolytic Tough Pitch (ETP) Copper Plate – Excellent Electrical Conductivity and Formability

Overview

C11000 Electrolytic Tough Pitch (ETP) Copper is one of the most widely used copper grades in industrial, electrical, and electronic applications due to its exceptional combination of high electrical and thermal conductivity, excellent formability, and good corrosion resistance. Our high-purity C11000 ETP copper plate meets or exceeds ASTM B187/B187M standards and is ideal for demanding applications where performance, reliability, and consistency are paramount.

Manufactured through a controlled electrolytic refining process, this copper plate maintains a minimum purity of 99.90% Cu, with oxygen content carefully balanced to optimize mechanical and electrical properties. Whether you're designing busbars, heat exchangers, electrical connectors, or architectural components, our C11000 copper plate delivers unmatched quality and performance.

Physical Properties

Available Dimensions & Tolerances

Our C11000 ETP copper plates are available in a wide range of standard and custom dimensions:

Tolerances comply with ASTM B209 or as per customer specification (e.g., ±0.05 mm for thickness in precision applications).

Why Choose High-Purity C11000 ETP Copper?

1. Unmatched Conductivity: With ≥100% IACS, it sets the benchmark for electrical efficiency—critical in power transmission and high-frequency electronics.
2. Reliable Performance: Consistent oxygen content ensures stable mechanical properties and prevents hydrogen embrittlement in reducing atmospheres.
3. Eco-Friendly & Recyclable: Copper is 100% recyclable without loss of properties, supporting sustainable manufacturing.
4. Global Compliance: Meets international standards including ASTM B187, UNS C11000, EN CW004A, and DIN 2.0090.
5. Traceability & Certification: Full material test reports (MTRs), RoHS/REACH compliance documentation, and batch traceability provided.

Processing & Fabrication Guidelines

C11000 ETP copper plate is highly workable using standard metalworking techniques:

• Cutting: Shearing, laser cutting, waterjet, or plasma (with appropriate settings to avoid oxidation).
• Forming: Excellent cold-forming capabilities; annealing recommended for severe deformation.
• Machining: Moderate machinability; use sharp tools and lubricants to reduce galling.
• Joining: Readily soldered, brazed, or welded (TIG/MIG with inert gas shielding recommended).
• Surface Treatment: Can be passivated, tin-plated, nickel-plated, or coated for enhanced corrosion resistance or aesthetics.

Avoid prolonged exposure to sulfur-containing atmospheres to prevent tarnishing.

Quality Assurance

Every batch of our C11000 copper plate undergoes rigorous testing, including:

• Spectrometric analysis for chemical composition
• Eddy current or four-point probe testing for electrical conductivity
• Tensile and hardness testing per ASTM E8/E18
• Ultrasonic inspection for internal defects (optional for critical applications)
• Dimensional verification with calibrated metrology tools

We maintain ISO 9001:2015 certification and offer full documentation for aerospace, medical, and energy sector clients.

Packaging & Delivery

To ensure product integrity during transit:

• Plates are wrapped in anti-tarnish paper and VCI film
• Palletized with wooden spacers and corner protectors
• Export-standard fumigated wooden crates available
• Just-in-time (JIT) delivery and inventory management services offered

Frequently Asked Questions (FAQ)

Q: Is C11000 suitable for vacuum or high-temperature applications?
A: Due to its oxygen content (~0.03%), C11000 may suffer from hydrogen embrittlement above 200°C in reducing atmospheres. For such environments, oxygen-free copper (e.g., C10100/C10200) is recommended.

Q: What’s the difference between C11000 and C10200?
A: C11000 contains controlled oxygen for improved hot workability and conductivity, while C10200 is oxygen-free (<0.001% O), making it better for welding and high-temperature service.

Q: Can you provide certified conductivity test reports?
A: Yes. We provide third-party verified conductivity reports (≥100% IACS) with every shipment upon request.

Q: Do you offer custom temper or surface finishes?
A: Absolutely. We can supply plates in annealed, half-hard, hard, or spring tempers, along with mirror-polished, brushed, or anti-reflective finishes.
