C11000 Electrolytic Tough Pitch (ETP) copper is the most widely utilized grade of copper globally, known for its exceptional electrical conductivity (minimum 101% IACS) and thermal properties. As an OEM C11000 copper sheet manufacturer, Sichuan Kepai New Materials Co., Ltd. recognizes the material's critical role in the "Green Transition." From the busbars in EV battery packs to the precision winding in renewable energy transformers, C11000 remains the industry gold standard.
The global copper market is currently undergoing a paradigm shift. With the rise of AI data centers requiring massive power densities and the electrification of transportation, the demand for high-purity copper sheets has surged. C11000, with its 99.90% purity, offers the perfect balance of performance and economic viability for large-scale industrial projects.
In the competitive landscape of metallurgical supply chains, Chinese manufacturers like Kepai New Materials offer distinct advantages that go beyond mere cost reduction. Our facility in Sichuan represents the pinnacle of "Industry 4.0" integration in copper alloy production.
By housing R&D, casting, rolling, and precision slitting under one 29,000 sqm roof, we minimize "Information Entropy." This vertical integration allows us to offer OEM C11000 copper sheet solutions with lead times significantly shorter than Western competitors. Whether you require specific tempers (O60, H02, H04) or non-standard thicknesses, our manufacturing agility ensures your project stays on schedule.
Our commitment to E-E-A-T principles is reflected in our certifications. We are not just a "factory"; we are a technical partner. We have passed ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. This ensures that every sheet of C11000 leaving our facility meets the stringent requirements of the aerospace, medical, and new energy sectors.
C11000 copper sheets are cold-rolled into busbars and battery connectors. Their high conductivity reduces heat generation, crucial for battery longevity and safety in modern EVs.
Leveraging the natural antimicrobial properties of 99.9% pure copper, our C11000 sheets are used in touch surfaces and medical shielding to prevent HAI (Hospital Acquired Infections).
High-purity ETP copper is vital for EMI/RFI shielding and power distribution units in avionics, where failure is not an option and material reliability is paramount.
Used in seawater desalination systems and heat exchangers, C11000 offers excellent corrosion resistance and biofouling prevention in harsh maritime environments.
1. Sustainability & Circular Economy: Global enterprises are now demanding "Green Copper." Kepai is leading this by implementing environmentally friendly production processes and maximizing the use of recycled copper cathodes without compromising 101% IACS purity.
2. Precision & Miniaturization: As electronics get smaller, the demand for ultra-thin, high-precision C11000 copper foil and thin sheets grows. We utilize advanced rolling mills to achieve tolerances within microns.
3. Supply Chain Resilience: Diversifying the procurement base is a top priority for Fortune 500 companies. Working with a direct C11000 copper supplier in China allows for better cost control and technical transparency compared to middle-man distributors.
When sourcing C11000 Copper Sheets, procurement officers should verify:
C11000 (ETP) contains a small amount of oxygen (0.02% to 0.04%), which helps in removing impurities but makes it susceptible to hydrogen embrittlement if welded. C10100 (OFC) is oxygen-free and suitable for high-vacuum and high-temperature welding applications.
Yes. We provide OEM services to supply C11000 in various tempers, from Soft Annealed (O60) to Extra Hard (H08), depending on your forming or structural requirements.
We use high-purity electrolytic copper cathodes and monitor the melting process with real-time spectrometers and conductivity meters to ensure compliance with international ASTM standards.
Our current production lines allow for widths up to 1000mm, with thicknesses ranging from 0.1mm to 100mm, catering to both foil and heavy plate requirements.
