Pure Copper Sheet C11000, T2, CU-ETP Copper Plate for Electrical and Industrial Applications

Introduction

Pure copper sheet C11000, also known as Electrolytic Tough Pitch (ETP) copper or T2 copper in Chinese standards, is one of the most widely used high-conductivity copper materials in the world. With a minimum copper content of 99.90%, C11000 offers exceptional electrical and thermal conductivity, excellent formability, and superior corrosion resistance—making it ideal for applications in electrical engineering, electronics, industrial machinery, heat exchangers, and architectural design.

Manufactured to meet international standards including ASTM B152, EN 13601, JIS H3100, and GB/T 2040, C11000 ETP copper plates are trusted by engineers and manufacturers globally for their consistent quality, reliability, and performance under demanding conditions.

This product information page provides a comprehensive overview of C11000 pure copper sheets, including technical specifications, key properties, common applications, and ordering guidance—optimized for both technical buyers and search engines like Google.

What Is CU-ETP (C11000) Copper?

CU-ETP (C11000) stands for Electrolytic Tough Pitch Copper, a designation defined by the Unified Numbering System (UNS). It is produced through electrolytic refining, resulting in extremely high purity with controlled oxygen content (typically 200–400 ppm). This oxygen helps improve hot workability but must be managed in reducing atmospheres to avoid hydrogen embrittlement.

Key characteristics:

• Non-alloyed (essentially pure copper)
• High electrical conductivity: ≥100% IACS (International Annealed Copper Standard)
• Excellent thermal conductivity: ~398 W/m·K
• Good ductility and cold-forming capability
• Natural antimicrobial properties
• Recyclable and sustainable

Key Advantages of C11000 Copper Plates

1. Unmatched Electrical Conductivity

C11000 is second only to silver in electrical conductivity among metals. This makes it the material of choice for busbars, transformers, switchgear, and power distribution systems where minimal energy loss is critical.

2. Superior Thermal Performance

Its high thermal conductivity ensures efficient heat dissipation—ideal for heat sinks, radiators, HVAC components, and refrigeration systems.

3. Excellent Formability & Machinability

C11000 copper can be easily stamped, bent, deep-drawn, or rolled without cracking. It also machines well with proper tooling, enabling complex component fabrication.

4. Corrosion Resistance

Resists atmospheric, water, and many chemical environments. Forms a protective patina over time, enhancing longevity in architectural cladding, roofing, and marine applications.

5. Antimicrobial Properties

Copper surfaces naturally kill bacteria, viruses, and fungi within hours—recognized by the EPA. Used in healthcare facilities, public spaces, and food processing equipment.

6. Sustainability & Recyclability

100% recyclable without loss of properties. Over 80% of all copper ever mined is still in use today—supporting circular economy goals.

7. Aesthetic Appeal

Warm reddish-gold color that ages gracefully to a distinctive green patina. Popular in interior design, sculptures, and luxury finishes.

Common Industrial & Electrical Applications

Why Choose C11000 Over Other Copper Grades?

• vs. C10200 (Oxygen-Free Copper): C11000 is more cost-effective and suitable for most ambient applications. C10200 is preferred only in high-vacuum or hydrogen-rich environments where oxygen must be avoided.
• vs. Brass/Bronze Alloys: C11000 offers far higher conductivity but lower strength. Alloys are chosen when mechanical strength or wear resistance is prioritized over conductivity.
• vs. Aluminum: Copper has ~60% higher conductivity and better joint reliability, though aluminum is lighter and cheaper—used mainly in overhead power lines.

Quality Assurance & Certification

Reputable suppliers of C11000 copper plates adhere to strict quality control protocols:

• ISO 9001-certified production
• Full traceability from cathode to finished product
• Spectrometric analysis for composition verification
• Mechanical testing per ASTM/EN standards
• Ultrasonic or eddy current testing for internal defects (optional)

Certificates provided:

• Material Test Report (MTR)
• Certificate of Conformity (CoC)
• RoHS / REACH compliance documentation
• Export documentation (e.g., COO, packing list)
