C11000 copper, commonly referred to as Electrolytic Tough Pitch (ETP) copper, represents the gold standard for electrical conductivity and thermal efficiency in industrial applications. As a premier Wholesale C11000 Copper Material Supplier, Sichuan Kepai New Materials Co., Ltd. understands that this material is more than just a metal—it is a critical component in the global transition toward renewable energy, high-speed telecommunications, and advanced aerospace engineering.
With a minimum conductivity of 100% IACS (International Annealed Copper Standard), C11000 is characterized by its excellent workability and corrosion resistance. However, the modern industrial landscape demands more than just raw specifications. Our C11000 solutions provide the information gain necessary for engineers to optimize for both performance and cost-efficiency.
Optimized for low-loss power transmission and sensitive electronic signal integrity.
Excellent ductility for deep drawing, stamping, and complex geometry forging.
100% recyclable material meeting RoHS and REACH international environmental standards.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production, and sales of high conductivity and high strength special copper alloys. We have revolutionized the market by focusing on Tellurium Copper and Oxygen-Free C11000 derivatives.
Our 29,000 square meter facility serves over 1,000 global customers, backed by 30+ patent certificates. We are not just a supplier; we are an engineering partner providing macro industry solutions.
The global demand for C11000 and related copper alloys is experiencing a structural shift. With the rise of New Energy Vehicles (NEV), copper usage per vehicle has tripled compared to traditional internal combustion engines. This surge requires suppliers to provide not just raw material, but localized support and compliance guarantees.
High-conductivity C11000 is vital for busbars, charging connectors, and battery interconnects to ensure thermal stability under rapid charging.
Ultra-smooth copper foil and high-purity rods are essential for signal transmission and heat dissipation in 5G base stations.
Photovoltaic systems and wind turbines rely on oxygen-free copper to maintain long-term reliability in harsh environmental conditions.
Leveraging copper's natural antimicrobial properties and precision conductivity for MRI and surgical tools.
Critical components for system efficiency, focusing on high-current power distribution units.
Lightweight, high-reliability copper wiring for data transmission and generator units.
Corrosion-resistant alloys designed for seawater biological fouling protection.
Global procurement requires strict adherence to ISO 9001:2015, ISO 14001:2015, and IATF 16949 standards. Sichuan Kepai ensures that every shipment is accompanied by detailed Material Test Reports (MTRs) and SGS certifications. Our localized support teams in major industrial hubs provide technical consultation and just-in-time delivery to mitigate supply chain risks.
C11000 (ETP) contains a small amount of oxygen (0.02% to 0.04%), which is ideal for most electrical applications. C10100 (OFHC) is 99.99% pure and oxygen-free, designed specifically for high-vacuum applications and hydrogen brazing where embrittlement is a concern.
We utilize an independent R&D team and a closed-loop production system. Every melt is sampled and tested for conductivity, tensile strength, and grain size before proceeding to the final shaping phase.
While pure copper is "sticky" during machining, our C11000 processing techniques improve its chip-breaking capabilities. For extreme precision, we often recommend our Tellurium Copper (C14500) as a high-performance alternative.
Standard stock items are shipped within 7-10 days. Custom alloy specifications or large-scale production runs typically range from 3 to 6 weeks, depending on the complexity and volume.
