In the era of rapid electrification and high-precision manufacturing, Tellurium Copper (C14500) has emerged as a critical material bridge. As a premier tellurium copper alloy manufacturer, Sichuan Kepai New Materials is at the forefront of this metallurgical revolution.
The demand for high-conductivity, free-cutting copper alloys is surging across North America, the EU, and East Asia. With the global transition to green energy, tellurium copper is no longer a niche material but a cornerstone for EV charging infrastructure and high-speed data transmission.
The EV sector requires connectors that can handle high current loads with minimal heat generation. Our custom tellurium copper offers up to 93% IACS conductivity, outperforming traditional brass in thermal management and electrical efficiency.
Weight-to-conductivity ratios and machinability are paramount. C14500's unique ability to be precision-machined into complex geometries without sacrificing electrical integrity makes it the preferred choice for avionics and satellite systems.
Established in May 2017, we are a high-tech private company specializing in R&D, production, and sales of high conductivity and high strength free cutting tellurium copper. Our 29,000 m² factory serves over 1,000 customers globally with 30+ patented technologies.
