In the realm of advanced metallurgy, C18700 Leaded Copper stands as a critical material for precision engineering. As a leading OEM C18700 Copper Alloy Manufacturer, Kepai New Material recognizes that modern industrial applications demand a unique convergence of 98% IACS electrical conductivity and superior machinability.
C18700 is primarily composed of copper with a strategic addition of approximately 1% lead. This lead content acts as an internal lubricant and chip breaker, allowing for ultra-high-speed machining without compromising the thermal or electrical integrity of the base metal. For global procurement managers, this translates to reduced tool wear, faster cycle times, and exceptionally smooth surface finishes.
Unlike standard pure coppers which are notoriously difficult to machine due to their "gummy" nature, C18700 allows engineers to design complex geometries for electrical connectors, switchgear components, and precision automotive sensors. By choosing Kepai as your manufacturer, you gain access to proprietary smelting techniques that ensure lead distribution is uniform, preventing structural weak points often found in lower-quality alloys.

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 facility in China leverages cutting-edge technology to serve the high-end manufacturing needs of the 21st century.
The industry is shifting toward miniaturization and high-power density. C18700 is becoming the standard for EV charging pins and 5G base station connectors due to its low contact resistance.
Chinese factories like Kepai offer a vertically integrated supply chain—from raw material smelting to precision finishing—ensuring stable pricing despite global copper market volatility.
We are pioneering environmentally friendly production. Our leaded copper processes strictly adhere to ISO14001:2015, balancing high performance with sustainable ecological responsibility.
Copper's antimicrobial properties combined with C18700's precision make it ideal for surgical tools and high-sensitivity diagnostic equipment components.
As an OEM manufacturer, we provide C18700 solutions for high-current connectors and battery management systems, enhancing overall system efficiency.
Reliability is non-negotiable. Our C18700 alloys are tested for extreme temperature resistance and signal integrity for aircraft generators and data systems.
Kepai is not just a manufacturer; we are an innovator. We have developed Oxygen-Free High Conductivity Tellurium Copper (OFT), which surpasses traditional grades in both conductivity and durability.
