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 special copper alloys.
As the world pivots toward Net-Zero 2050, the demand for 100% high-purity copper has surged by 45% in the last three years. Tier-1 manufacturers in North America and Europe are prioritizing "High-Performance Oxygen-Free Copper" for EV charging infrastructures and solar inverters to minimize energy loss.
Modern EVs require copper with >100% IACS conductivity and superior thermal stability. Kepai’s tellurium copper alloys (C14500) provide the perfect balance between high conductivity and machinability, reducing connector manufacturing costs by 20% compared to traditional pure copper machining.
Reliability is non-negotiable in aerospace. High-purity beryllium copper and oxygen-free alloys are essential for data transmission parts and generators where environmental stress and thermal fluctuations are extreme.
Copper's inherent antimicrobial properties, combined with Kepai's precision manufacturing, enable the creation of surgical tools and diagnostic equipment surfaces that active-suppress bacterial growth. Our high-conductivity copper ensures signal integrity in MRI and high-frequency medical scanners.
Marine environments require more than just conductivity; they demand resistance to biofouling and seawater erosion. Our specialized leaded bronze and sulfur copper alloys are engineered for undersea connectors and offshore power transmission systems.
Kepai provides the core conductive materials for Plasma Cutting Electrodes and Photovoltaic Energy Storage. Our OFT (Oxygen-Free High Conductivity Tellurium Copper) is the gold standard for high-current connectors in battery management systems.
Mastering the oxygen-free smelting process to achieve <10ppm oxygen content while maintaining trace element precision for free-cutting tellurium copper (C14500).
Developing Nickel-Silicon-Chromium precipitation strengthened alloys (C19160) to meet the demand for ultra-miniaturized connectors that require high spring force and conductivity.
Implementing AI-driven melting controls to optimize grain structure and achieving 100% recyclable "Green Copper" production to comply with the strictest EU environmental mandates.
Kepai is fully certified under ISO 9001:2015, ISO 14001:2015, and OHSAS 45001:2018. Every batch of 100% copper material undergoes rigorous spectroscopic analysis to ensure 100% compliance with RoHS and REACH standards.
With a market distribution spanning from domestic China to high-reputation exports in Europe and SE Asia, we provide localized technical consultation to help engineers select the optimal alloy for their specific manufacturing constraints.
Our 29,000 sqm facility ensures high-volume availability. We maintain strategic reserves of high-purity cathodes to buffer against global market volatility, ensuring "just-in-time" delivery for our 1000+ global partners.
Beryllium copper provides the highest strength of all available copper-beryllium alloys. Tensile strength can exceed 200 ksi (1380 MPa). Ideal for precision spring clips and highly reliable conductive elements.
Hailed for its "Free-Cutting" properties, C14500 offers 85% machinability compared to 20% for pure copper. It maintains >90% IACS conductivity, making it the premier choice for plasma torch tips and high-speed lathe production.
A nickel-silicon precipitation strengthened copper alloy. It offers excellent electrical conductivity and outstanding softening resistance for high-temperature electrical applications.
Our OFT series represents the peak of copper purity. By removing oxygen, we eliminate hydrogen embrittlement risks, making it indispensable for vacuum electronics and high-purity industrial piping.
Excellent wear resistance and fatigue properties. Added tin and phosphorus ensure that C54400 components outlast standard brass in high-friction environments like bushings and bearings.
Known as the "King of Free-Cutting", this alloy is the industry standard for high-volume automated manufacturing of precision screws, nuts, and fluid system components.
Addressing the technical concerns of copper procurement professionals.
Standard tellurium copper contains oxygen which can cause hydrogen embrittlement during brazing or welding. Kepai’s Oxygen-Free process eliminates this risk, providing higher structural integrity for high-power electrical connectors.
We use advanced SPECTRO analysis for every melt. Our 100% copper series focuses on C10100 and C11000 grades, ensuring a minimum of 99.99% purity for high-vacuum and superconducting applications.
Yes. Our independent R&D team works directly with global engineers to develop proprietary alloy ratios. We have already secured over 30 patents for such specialized materials.
Typical lead times range from 2 to 6 weeks depending on the alloy complexity and volume. We offer expedited shipping through major global ports to maintain your production schedule.
