Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech pioneer specializing in high conductivity and high strength tellurium copper and phosphor copper alloys. Our mission is to bridge the gap between traditional metallurgy and the future of industrial demand.
With 30+ patent certificates and a dedicated internal research team, we don't just supply; we innovate. Our development of oxygen-free highly conductive tellurium copper has set new industry benchmarks for plasma cutting and new energy vehicle components.
Beyond our dominant domestic share, Kepai’s footprint spans the globe. We provide high-reputation export services to clients across Europe, North America, and Southeast Asia, ensuring local compliance and technical support.
Phosphor copper (often classified within the phosphor bronze family) has undergone a dramatic transformation. Originally valued for its deoxidizing properties in foundry applications, modern engineering now demands C51100, C54400, and C51000 alloys for their superior fatigue resistance and elasticity. As the world moves toward 5G infrastructure and IoT connectivity, the requirement for miniaturized, reliable connectors has placed phosphor copper at the center of the "Smart Revolution."
As a leading custom phosphor copper factory, we have observed a 40% increase in demand for alloys with precisely controlled phosphorus content. This precision is vital; even a 0.01% deviation in phosphorus can alter the conductivity and tensile strength of the material, impacting the performance of critical aerospace and medical device connectors.
Procurement teams from Fortune 500 companies are no longer just looking for a "supplier"—they are seeking "strategic reliability." The current global landscape is plagued by raw material volatility and energy constraints. By partnering directly with an integrated phosphor copper factory like Sichuan Kepai, buyers gain "Information Gain" through transparent technical data, lead-time predictability, and ESG-compliant manufacturing processes.
Our macro-industry solutions focus on lifecycle management. From the initial smelting stage in our 29,000 sqm facility to the final cold-rolling process, every step is monitored to meet IATF 16949 standards, providing a "Reliability Index" that traditional traders cannot match.

Our company has passed ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. Every shipment is accompanied by a Material Test Report (MTR) to ensure full traceability.
We reduce industrial impact by using eco-friendly free-cutting copper alloys, meeting REACH and RoHS standards for international market access.
We offer localized logistics support, door-to-door delivery options, and technical consulting to solve complex metallurgical challenges on-site.
C51100 offers an exceptional balance of strength, fatigue resistance, and electrical conductivity. It is highly resistant to corrosion and stress relaxation, making it the industry standard for electrical springs and high-cycle connectors.
We utilize proprietary vacuum melting and controlled atmosphere casting technologies. This prevents oxygen absorption during the smelting process, resulting in a material with superior weldability and higher conductivity than standard tellurium copper.
Yes. As a custom factory, our R&D team can adjust phosphorus, tellurium, beryllium, or sulfur content to meet specific mechanical or electrical requirements provided by your engineering team.
Standard alloy specifications are typically available in 2-4 weeks. Custom alloy formulations or specific dimensions may take 6-8 weeks, depending on the complexity of the metallurgical processing required.
We understand the importance of innovation. We offer prototyping services for high-tech industries to help validate material performance before moving to mass production.
