C11000, known as Electrolytic Tough Pitch (ETP) copper, represents the global standard for electrical conductivity. With a minimum copper content of 99.90%, C11000 is meticulously refined to offer an IACS (International Annealed Copper Standard) rating of 100% or higher. At Sichuan Kepai New Materials Co., Ltd., we leverage advanced continuous casting and rolling technologies to ensure that our C11000 alloy material exceeds the standard industry requirements for purity and surface finish.
The semantic importance of C11000 in modern industry cannot be overstated. As the backbone of the "Electrification of Everything," this material is the primary choice for busbars, power transmission lines, and high-current electrical components. Our manufacturing process focuses on eliminating the risks of internal oxidation and ensuring a uniform grain structure, which is critical for bending and forming applications in demanding environments.
In the localized context of Europe and North America's transition to renewable energy, C11000 serves as the critical conductive interface for Utility-Scale Battery Energy Storage Systems (BESS). Its low thermal resistance prevents localized hotspots during rapid charge cycles.
With the surge of electric vehicles in the Asia-Pacific region, our C11000 busbars are utilized in DC fast-charging stations. The material's high ductility allows for complex geometries in compact charging modules without fracturing.
Modernization of the US power grid requires high-purity C11000 foils and strips for transformer windings. Kepai provides tailored thickness tolerances as low as ±0.005mm to enhance transformer efficiency and reduce eddy current losses.
Precision robotics in Germany and Japan rely on C11000 for high-current connectors. Our alloy ensures long-term reliability in harsh environments, resisting corrosion and maintaining stable contact resistance over millions of operational cycles.
As a leading Chinese copper alloy factory located in Sichuan, Kepai New Materials benefits from a robust local ecosystem and significant logistics advantages. Our 29,000 square meter facility is equipped with vertical integration—from raw material melting and casting to precision extrusion and final surface treatment.
Supply Chain Security: In an era of geopolitical volatility, Kepai ensures resilience through diversified raw copper sourcing and an immense on-site buffer stock. This allows us to provide stable pricing and lead times that are typically 20-30% shorter than our Western competitors.
Efficiency Metrics: Our ISO 9001 and IATF 16949 certifications are not just badges; they drive our Lean Six Sigma production approach. We achieve 99.8% first-pass yield on C11000 orders, reducing waste and passing the cost savings directly to our global clientele.
Development of oxygen-free variants (C10100/C10200) that maintain the cost-effective profile of C11000 while eliminating hydrogen embrittlement for high-vacuum and cryo-applications.
Research into graphene-infused copper alloys. Our goal is to break the 105% IACS barrier, providing the next generation of materials for high-speed rail and aerospace propulsion systems.
Implementing a "Closed-Loop" recycling program where industrial scrap from our C11000 clients is re-melted and certified to original performance standards, reducing the carbon footprint of copper production by 60%.
Our C11000 material is fully compliant with RoHS, REACH, and Conflict Minerals regulations. We provide full material traceability reports (MTRs) with every shipment, ensuring your peace of mind.
Led by industry veterans, our R&D center specializes in high-conductivity tellurium copper and oxygen-free copper. We have successfully solved grain coarsening issues in high-temperature soldering for major electronics brands.
Utilizing SPECTRO spectrometers and advanced conductivity meters, we verify the chemical composition and electrical properties of every heat number. Consistency is our core competitive advantage.
While both have high conductivity, C11000 (ETP) contains a small amount of oxygen (usually as cuprous oxide). C10100 (OFE) is 99.99% pure and oxygen-free, making it superior for applications requiring high-temperature heating in hydrogen atmospheres to prevent hydrogen embrittlement.
Yes. We specialize in custom-extruded profiles, wide-format foils, and heavy-gauge busbars. Our CNC machining center can also provide semi-finished components based on your technical drawings.
Standard stock items ship within 3-7 days. Custom production runs typically take 15-25 days. We have established partnerships with major sea and air freight carriers to ensure timely delivery to the USA, EU, and SE Asia.
C11000 has excellent corrosion resistance due to the formation of a protective patina. However, for extreme coastal environments, we recommend our tin-plated or nickel-plated C11000 variants to prevent oxidative buildup at contact points.
Yes, we are IATF 16949 certified, which is the global standard for automotive quality management systems. Our materials are already used in Tier-1 EV supply chains.
