C11000 (UNS C11000, ASTM B152/B187, ISO CW004A)
Also known as phosphorized copper or ETP copper (Electrolytic Tough Pitch), with a minimum copper content of 99.90% and trace oxygen (≤0.06%).
Product Features
Exceptional electrical conductivity (~100% IACS), ideal for electrical applications.
High thermal conductivity (394 W/m·K), suitable for heat exchangers and cooling systems.
Excellent ductility and formability, enabling cold working and complex shaping.
Good corrosion resistance in atmospheric and aqueous environments.
Susceptible to "hydrogen embrittlement" in high-temperature (>370°C) reducing atmospheres.

C11000 Material Core Advantages
Ultra-high conductivity for electrical and thermal systems.
Superior formability for intricate designs in electronics and machinery.
Cost-effective alternative to silver in conductive applications.
Resistance to atmospheric corrosion for long-term durability.
Product Applications
Electrical: Wiring, busbars, connectors, transformers.
Thermal Management: Heat exchangers, radiators, solar heating components.
Industrial: Pipes, fasteners, stamped parts.
Aerospace: Conductive components and heat dissipation systems.
Processing Guidelines
Machining: Use sharp tools with low cutting speeds and lubrication to prevent overheating.
Welding: Avoid high-temperature reducing environments (e.g., hydrogen-rich) to prevent hydrogen embrittlement.
Annealing: Perform at 500–700°C to restore ductility after cold working.
Forming: Suitable for cold rolling, bending, and stamping due to high ductility.
Key Application Scenarios
High-current electrical transmission systems (e.g., power grids).
Precision electronic connectors in consumer devices.
Corrosion-resistant plumbing and marine fittings.
FAQs
Q1: Why is C11000 prone to hydrogen embrittlement?
A: Trace oxygen reacts with hydrogen in reducing atmospheres, forming water vapor that causes micro-cracks.
Q2: How does material C11000 compare to oxygen-free copper (OFHC)?
A: C11000 has slightly lower conductivity (~100% IACS vs. 101% for OFHC) but is more cost-effective for general applications.
Q3: Can C11000 be used for welding?
A: Yes, but avoid processes involving hydrogen (e.g., gas welding). Soldering or brazing is preferred.
