Precision-engineered solutions for high-conductivity and free-cutting applications.
As the world pivots toward electrification, the demand for high-performance copper alloys—specifically Tellurium Copper (C14500) and Sulfur Copper (C14700)—has reached an all-time high. In the current industrial landscape, standard copper often fails to meet the dual requirements of high electrical conductivity and superior machinability. Semantic search data reveals that procurement directors in the EU and North America are increasingly shifting their intent toward "oxygen-free" and "low-impurity" variants to prevent hydrogen embrittlement in high-voltage applications.
Located in the heart of China's industrial manufacturing hub, Sichuan Kepai New Materials Co., Ltd. (Established 2017) represents the pinnacle of "China Factory 4.0." Our facility integrates AI-driven metallurgy with real-time quality monitoring. In an era of global supply chain volatility, Kepai offers a resilient alternative with vertical integration—from raw material R&D to final extrusion and precision machining.

How Kepai’s Sulfur and Tellurium Copper alloys solve real-world engineering challenges.
Our sulfur-copper alloys are used in high-current charging pins and terminal blocks, where high speed machining is required without sacrificing thermal conductivity.
High-strength beryllium copper components for generators and data transmission parts that require extreme reliability in high-stress environments.
Utilizing the anti-microbial properties of pure copper and the precision of our free-cutting alloys for surgical components and imaging equipment.
While both are free-cutting copper alloys, Sulfur Copper (C14700) generally offers slightly better electrical conductivity and is often more cost-effective for high-volume automated screw machine operations where the extreme thermal resistance of Tellurium is not the primary requirement.
We adhere to strict IATF 16949 (Automotive Quality Management) and ISO 9001 standards. Every batch of our copper alloy undergoes spectral analysis and mechanical testing, with full traceability provided to the client. Our R&D team consists of industry veterans with over 20 years of experience in non-ferrous metallurgy.
By sourcing directly from Sichuan Kepai, you bypass middleman markups and gain direct access to our engineering team for "Custom" alloy specifications. Our China 4.0 infrastructure ensures a 30% faster production cycle compared to traditional Western smelters.
