In the hierarchy of non-ferrous metals, Copper Alloy C11000, also known as Electrolytic Tough Pitch (ETP) copper, stands as the gold standard for electrical and thermal conductivity. As the world pivots toward decarbonization, electrification, and high-speed data transmission, the role of a premier C11000 manufacturer has evolved from a simple material supplier to a strategic technical partner. C11000 offers a minimum conductivity rating of 101% IACS, making it indispensable for the core components of the green energy revolution.
For global procurement officers, sourcing C11000 is no longer just about price-per-kilogram; it is about metallurgical purity, grain structure uniformity, and logistical resilience. Sichuan Kepai New Material Co., Ltd. addresses these needs by integrating advanced smelting technologies with a rigorous understanding of global industrial standards.
Established in 2017, Sichuan Kepai New Material Co., Ltd. is a high-tech enterprise integrating research and development, production, and sales. Currently, our factory covers an area of approximately 9,000 square meters. We primarily engage in the production of strategic emerging new materials, including special copper alloys such as tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper.
Our products are vital for high-tech fields like new energy vehicles, 5G technology, laser cutting, and lithium battery relays. We adhere to the business philosophy of "innovation-driven development, quality wins the market," committed to providing customers with high-end copper alloy materials that promote industrial upgrading.

Global demand for C11000 busbars and connectors is surging due to the upgrading of aging power grids in the US and Europe. Engineers require ETP copper that can withstand high voltage while minimizing resistive heat loss.
From charging stations to battery interconnects, C11000 is the backbone. Manufacturers demand high-ductility copper that can be easily formed into complex shapes without compromising electrical integrity.
Solar and wind farms require massive quantities of copper for inverters and transformers. The procurement focus is moving toward suppliers who can guarantee RoHS and REACH compliance.
Technological innovation is the core competitiveness of Sichuan Kepai. Our team of senior experts continuously explores the unknown boundaries in the field of new copper alloy materials. Through a combination of independent R&D and industry-university-research collaboration, we have reached international advanced levels in high-performance tellurium copper, lead copper, and sulfur copper.
Our product system is diverse, covering basic materials to high-end customization, including pure copper, oxygen-free copper, nickel tellurium copper, tin bronze, and chromium zirconium copper.
Refining oxygen content to below 20ppm while maintaining the cost-effectiveness of C11000 for mass production.
Developing advanced anti-oxidation coatings that prevent conductivity degradation in harsh industrial environments.
Utilizing machine learning to optimize the cooling and extrusion processes for superior isotropic grain structures.
Transitioning to 100% closed-loop recycling systems for copper scrap in the C11000 manufacturing cycle.

Our C11000 production strictly adheres to ASTM B187 (for busbars), ASTM B152 (for sheet/plate), and equivalent international standards to ensure plug-and-play compatibility with your designs.
We provide full documentation for RoHS, REACH, and Conflict Minerals reporting, supporting your corporate ESG goals and easing the path through customs and regulatory audits.
With strategic hubs and optimized shipping lanes, we offer "just-in-time" delivery solutions for our partners in North America, Southeast Asia, and Europe.
C11000 (ETP) contains a small amount of oxygen (0.02% to 0.04%), which helps in refining the material. C10200 is Oxygen-Free Copper. While C11000 is excellent for most electrical applications, C10200 is preferred for high-vacuum applications or where hydrogen embrittlement is a concern during brazing.
Yes, as a leading manufacturer, Sichuan Kepai offers customized extrusion, drawing, and machining to meet specific blueprint requirements, including custom busbar geometries and specialized wire diameters.
We use high-purity electrolytic cathodes and maintain strict control over impurities like phosphorus, arsenic, and lead, which are known to significantly drop copper's conductivity even in trace amounts.
Depending on the order volume and customization, typical lead times range from 2 to 6 weeks, supported by our efficient logistics network radiating from our Sichuan industrial base.
Unlock the potential of your industrial designs with the purest copper alloys on the market. Our technical team is ready to assist you.
