C11000, commonly known as Electrolytic Tough Pitch (ETP) copper, represents the global standard for electrical and thermal conductivity. As a leading manufacturer, Sichuan Kepai New Materials provides the definitive guide to why this material remains the backbone of modern engineering.
With 99.9% purity, C11000 copper offers an IACS electrical conductivity rating of 101%. Unlike oxygen-free copper, the trace amounts of oxygen in C11000 contribute to its specific physical properties, making it ideal for busbars, electrical terminals, and high-performance heat exchangers. Its ease of soldering and welding makes it a favorite for engineers optimizing assembly line efficiency.
China has emerged as the global hub for high-grade copper production. Leveraging mature supply chains, Sichuan Kepai integrates raw material sourcing with advanced extrusion and rolling technologies. This vertical integration allows us to provide:
The transition to New Energy Vehicles (NEVs) and 5G infrastructure has spiked the demand for high-purity conductive materials. We are witnessing a shift where C11000 is no longer just "raw material" but a "precision component." Whether it's thin sheets for flexible busbars in battery packs or robust plates for laser cutting machinery, our local application team works closely with global firms to ensure the material performs under extreme thermal loads.
Since 2017, Sichuan Kepai has grown from a specialized research unit into a comprehensive 9,000 sqm production facility. We bridge the gap between laboratory-grade innovation and mass-production reliability.
Our testing suite includes eddy current conductance instruments, universal testing machines, and metallographic polishing. We don't just ship products; we ship verified performance data.
Rooted in Sichuan, radiating to the world. We support international engineering firms with standardized compliance, ensuring our C11000 copper meets international ASTM/DIN/JIS standards.
C11000 contains a small amount of oxygen, making it slightly harder and more cost-effective for general electrical applications, whereas C10100 is oxygen-free, designed for hydrogen environments to prevent embrittlement. For most electrical busbar applications, C11000 is the superior value choice.
Yes. As a factory direct manufacturer, we offer precision rolling services ranging from foil-thin gauges to heavy plates. Custom tolerances are managed via our high-precision milling equipment.
We maintain an optimized inventory of standard C11000 specifications. For custom orders, production typically aligns with a 15-30 day window, depending on the volume and specific processing requirements.
