Compliance & Standards
Our C11000 copper rods are manufactured and tested in accordance with:
- ASTM B187: Standard Specification for Copper Bus Bar, Rod, and Shapes
- UNS C11000: Unified Numbering System designation
- EN 13601: Copper and copper alloys – Rod for electrical purposes (Cu-ETP)
- ISO 1337: Wrought copper – Chemical composition
- IEC 60193: Methods for measuring electrical resistivity of copper
All products are RoHS and REACH compliant. Mill Test Reports (MTRs) per EN 10204 3.1 are provided upon request.
Typical Applications
| Industry | Application Examples |
|---|---|
| Electrical Power | Busbars, transformer windings, switchgear components |
| Renewables | Solar inverter conductors, EV charging infrastructure |
| Electronics | Connectors, terminals, lead frames, PCB through-holes |
| Industrial | Grounding rods, lightning protection systems |
| Transportation | Railway electrification, battery interconnects (EVs) |
| Construction | Building grounding networks, architectural shielding |
| Marine | Cathodic protection anodes, shipboard electrical systems |
Due to its corrosion resistance and conductivity, C11000 is especially favored in coastal and high-humidity environments where long-term reliability is critical.

- Coiled Rods (≤20 mm): Neatly coiled on wooden spools or plastic reels, shrink-wrapped.
- Surface Protection: Ends capped or deburred; optional anti-tarnish coating available.
- Marking: Each bundle labeled with grade, diameter, heat number, length, weight, and compliance info.
- Shipping: Export-ready packaging compliant with ISPM 15 (for wooden materials). Suitable for ocean, air, and land freight.
Storage: Keep in dry, low-humidity environments. Avoid contact with acidic or sulfur-containing atmospheres to prevent tarnishing.
Frequently Asked Questions (FAQ)
Q1: Is C11000 suitable for welding?
A: C11000 can be welded using TIG or MIG with inert gas shielding, but porosity may occur due to oxygen content. For critical welded joints, consider oxygen-free copper (C10100/C10200).
Q2: Can this copper rod be used in hydrogen-rich environments?
A: No. The oxygen in ETP copper reacts with hydrogen at elevated temperatures (>200°C), causing steam formation and internal cracking (hydrogen embrittlement). Use deoxidized or oxygen-free copper instead.
Q3: What’s the difference between C11000 and C10100?
A: C11000 contains 200–400 ppm oxygen for improved castability and conductivity; C10100 is oxygen-free (<0.001% O), making it safer for high-temperature reducing atmospheres.
Q4: How is conductivity verified?
A: We use eddy current testing per ASTM E1004 to non-destructively confirm ≥100% IACS conductivity on every production batch.
Q5: Do you offer cut-to-length services?
A: Yes. Precision saw-cutting with ±0.5 mm tolerance is available for diameters up to 150 mm.
Q6: Is this product RoHS compliant?
A: Yes. All C11000 rods meet EU RoHS Directive 2011/65/EU and contain no restricted substances above threshold limits.
Q7: What is the typical lead time?
A: Standard sizes: 2–3 weeks. Custom diameters or large-volume orders: 4–6 weeks.
