Addressing the electrification boom with high-performance Tellurium Copper (TeCu) and Beryllium Copper (BeCu). We produce alloys that achieve over 93% IACS electrical conductivity without sacrificing structural integrity or machinability.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private enterprise focused on the manufacturing, R&D, and global supply of premium copper alloys.
A technical deep-dive into our core OEM alloy portfolio. Engineered for precision cutting, longevity, and superior conductivity.
C19160 (CuNiSiCr) is a heat-treatable nickel-silicon precipitation-strengthened copper alloy. Engineered to meet the demanding requirements of aerospace electrical connectors, C19160 presents high strength, excellent conductivity, and high resistance to thermal softening. Ideal for components operating under high structural and thermal loads.
A benchmark engineering material, C26000 achieves a calculated balance of cold-forming properties, excellent ductility, and moderate cost. It is widely specified for deep-drawn shells, stamped electrical terminals, radiator components, and complex automotive casings.
Our C51100 (CuSn4) phosphor bronze features high elasticity, fatigue resistance, and exceptional resistance to chemical corrosion. Combined with C54400, which has added lead for improved free-cutting performance, these alloys serve as industry standards for contact springs, bushings, bearings, and heavy-load wear plates.
By keeping oxygen content minimal, we prevent hydrogen embrittlement during brazing or welding. OFT Tellurium Copper provides over 93% IACS conductivity while offering a machinability rating of 85% compared to free-cutting brass (C36000), lowering tool wear significantly during high-volume CNC runs.
Why Fortune 500 manufacturers and industrial sourcing departments partner with Sichuan Kepai.
Pure copper (C11000) is notoriously difficult to machine due to its high ductility and stickiness, resulting in long, stringy chips that nest around tooling. Our tellurium copper alloys solve this by introducing microscopic telluride phases that act as chip breakers, allowing fast cutting speeds and clean finishes.
Electric vehicle (EV) charging stations and high-voltage distribution units demand components capable of carrying hundreds of amperes without overheating. Kepai's C14500 and OFT tellurium copper connectors ensure minimal contact resistance, protecting battery and charger electronics.
For aerospace actuator bushings, landing gear wear pads, and subsea oil and gas valves, beryllium copper (C17200, C17300, C17500) provides tensile strength exceeding 1380 MPa (200 ksi), comparable to high-strength alloy steels, while retaining non-magnetic properties and spark resistance.
Investing in green metallurgy, low-oxygen melting processes, and next-generation alloy design.
Advancing vacuum melting techniques to lower oxygen levels in high-conductivity tellurium copper to below 5 ppm, eliminating embrittlement during welding.
Developing bismuth-alloyed and silicon-alloyed free-cutting copper to replace leaded formulations, aligning with RoHS and REACH initiatives.
Utilizing sensor-driven thermal treatment lines to ensure consistent grain structures, matching tolerances for micro-machined connectors.
Active participation in drafting ISO and GB standards for copper alloys, maintaining leadership in regional and international material specs.
Where our custom metal components are deployed across the globe.
Copper possesses natural antimicrobial, anti-inflammatory, and antioxidant properties. Our copper components are deployed in hygienic medical interfaces, shielding enclosures, and high-conductivity wiring in diagnostic instruments.
High thermal and electrical conductivity is critical for electric powertrains. Our tellurium copper busbars, charging pins, and battery terminals enhance overall system efficiency and charge rates.
Copper-beryllium and chromium-zirconium copper components are used in high-output generators, actuator bushings, and landing gear systems where thermal stability is paramount.
We forge corrosion-resistant copper-nickel and bronze alloys designed to withstand saltwater exposure, biofouling, and high mechanical pressure in offshore structures.
Providing precision tellurium copper electrodes and electrode holders that withstand extreme temperatures and electrical wear, reducing consumable replacement cycles.
High-reliability copper distribution blocks and connectors engineered for large solar arrays and commercial battery energy storage systems (BESS).
Exporting to over 30 countries with full customs compliance and supply chain transparency.
In addition to maintaining a high domestic market share for custom copper alloys, Kepai has built a robust international logistics network. We ship systematically to North America, Europe, Southeast Asia, and South America, ensuring all exports include Mill Test Certificates (MTC), chemical analysis sheets, and conformance reports.
