C11000, known as ETP Copper, is the global benchmark for high conductivity. With a minimum purity of 99.90%, it offers an IACS (International Annealed Copper Standard) conductivity rating of 101%. As a leading Wholesale C11000 Copper Bar Company, we ensure our materials meet ASTM B187 and EN 13601 standards, providing unmatched reliability for busbars, electrical switchgears, and power transmission components.
Beyond conductivity, C11000 exhibits excellent thermal conductivity, making it ideal for heat exchangers and high-power electronic cooling. Its ductility allows for complex forming, deep drawing, and forging. Our factory utilizes vacuum casting and continuous extrusion processes to eliminate internal porosity, ensuring that each copper bar maintains structural integrity under extreme electrical loads.
In the age of strict environmental regulations, our C11000 copper bars are fully RoHS and REACH compliant. We implement IATF 16949 quality management systems to serve the automotive industry, specifically for electric vehicle (EV) battery packs and charging infrastructure. Every shipment is accompanied by a mill test certificate (MTC) documenting chemical composition and conductivity testing.
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 free cutting tellurium copper and other special copper alloys.
Our company has established its own independent R&D team, equipped with a complete production system and mature production technology. This allows us to have deep knowledge in the production of high-performance conductive materials. In addition to the production of traditional copper alloys, we have also developed a new type of highly conductive oxygen-free tellurium copper. Compared with traditional copper tellurium, this material has lower oxygen content and higher stability, making it perfect for high-speed automated machining.
Located in the industrial hub of Sichuan, Kepai leverages China's sophisticated logistics network. We offer seamless shipping to major ports (Shanghai, Ningbo, Shenzhen) and provide "DDP" (Delivered Duty Paid) services for international buyers, mitigating the complexities of cross-border procurement.
By sourcing raw electrolytic copper directly from primary smelters and utilizing high-volume continuous casting, we provide wholesale pricing that is significantly more competitive than European or North American distributors without compromising on the ASTM C11000 specification requirements.
We don't just sell "off-the-shelf" bars. We offer localized support including custom dimensions, surface plating (Tin, Silver, or Nickel), and specialized edge conditioning (rounded, square, or chamfered) to meet the precise requirements of regional electrical codes in the EU, USA, and SE Asia.
The global push for solar and wind energy is driving massive demand for C11000 copper bars. Photovoltaic inverters and wind turbine generators require high-conductivity busbars to minimize energy loss. We are currently scaling production to meet the 2030 Net-Zero targets of our global partners.
EV charging stations and battery management systems (BMS) are the new frontiers. C11000's ability to handle high currents while remaining ductile for vibration-heavy automotive environments makes it irreplaceable. We are collaborating with Tier-1 automotive suppliers to develop thinner, high-performance copper foils and bars.
AI processing units and data centers consume unprecedented amounts of power. High-purity copper bars are essential for the power distribution units (PDUs) within these centers. Our C11000 material provides the reliability needed for 24/7 uptime in critical digital infrastructure.
MRI shielding and diagnostic tools utilizing non-magnetic C11000 properties.
High-voltage busbars and battery interconnects for efficient EV performance.
Lightweight, high-conductivity wiring and generators for modern avionics.
Corrosion-resistant copper alloys for desalination and marine structures.
When sourcing from a Wholesale C11000 Copper Bar Company, engineers often ask: "Should I upgrade to Oxygen-Free Copper (OFC)?"
Growth Director's Note: For 90% of industrial power distribution applications, C11000 offers the absolute best performance-to-cost ratio. Our "High-Conductivity Oxygen-Free Tellurium Copper" innovation bridges the gap by offering the purity of OFC with the machinability of specialized alloys.
In addition to high share of the domestic copper alloy market, Kepai has exported to overseas clients with high reputation in Europe, America, and Southeast Asia.
Our company has passed ISO9001:2015, ISO14001:2015 and OHSAS 45001:2018 certifications.
