Pure Copper Materials FAQ
Common questions about pure copper materials for electrical applications and our services.
Why is pure copper better than brass for electrical applications?
Pure copper offers 101% IACS electrical conductivity compared to brass at only 28-37% IACS. For electrical applications, this means significantly lower power loss, reduced heat generation, and improved system efficiency. Brass is optimized for machining, while pure copper is engineered for maximum electrical performance.
What's the difference between C11000 and C10200 copper grades?
C11000 (ETP - Electrolytic Tough Pitch) contains ≥99.90% copper with 101% IACS conductivity. C10200 (OF - Oxygen-Free) contains ≥99.95% copper with 103% IACS conductivity and better high-temperature performance. C10200 is preferred for critical electrical applications requiring maximum conductivity and thermal performance.
Do you provide material traceability for electrical applications?
Yes. Every pure copper shipment includes complete Mill Test Certificates (MTC) with verified electrical conductivity testing, chemical composition analysis, and mechanical properties. We provide full batch traceability documentation to ensure compliance with electrical industry standards and quality requirements.
Can pure copper be CNC machined for electrical components?
Yes. While pure copper is softer than brass, it can be precision CNC machined with proper tooling and parameters. Our engineers optimize cutting speeds, tool geometry, and workholding to prevent deformation and achieve tight tolerances for electrical components like busbars, connectors, and heat sinks.
