In the contemporary landscape of high-precision manufacturing, Beryllium Copper (BeCu) stands as the ultimate "Master Alloy." As a premier Beryllium Copper Sheets Factory & Exporter, Sichuan Kepai New Materials addresses the critical demand for materials that refuse to compromise between mechanical strength and electrical conductivity.
Globally, the shift toward 5G infrastructure, electric vehicle (EV) power systems, and aerospace miniaturization has placed BeCu at the center of innovation. Unlike standard copper alloys, our BeCu sheets (specifically C17200 and C17500) provide tensile strengths exceeding 1380 MPa while maintaining thermal conductivity that outperforms stainless steel by a factor of five. This unique duality allows engineers to design smaller, more reliable components that operate in extreme thermal environments.

Established in May 2017, we are a high-tech private company specializing in R&D, production, and sales of high conductivity and high strength special copper alloys. Our mission is to bridge the gap between material science and industrial application through the innovation of Oxygen-free high conductivity tellurium copper and Beryllium Copper alloys.
Utilized in high-cycle battery contacts for smartphones and precision spring clips for 5G modems. The fatigue resistance of our C17200 sheets ensures millions of connection cycles without signal degradation.
Applied in heavy-duty relays and fast-charging connectors. Our materials withstand the high vibration and thermal spikes inherent in modern EV battery management systems (BMS).
Used for non-sparking safety tools and bushings in landing gears. The non-magnetic properties of Beryllium Copper are essential for sensitive avionic instrumentation.
As the industry moves toward greener manufacturing, Sichuan Kepai is spearheading the development of Low-Beryllium and Beryllium-Free Alternatives that mimic the performance of traditional BeCu while simplifying the recycling process. Our R&D department is currently focusing on:
In an era of global supply volatility, Sichuan Kepai offers a stable, vertically integrated manufacturing hub. Our facility in Sichuan benefits from proximity to raw material sources and a highly developed logistics network reaching ports in Shanghai and Shenzhen within days.
By eliminating intermediaries, we reduce lead times by 30% compared to Western stockists. Our real-time inventory management ensures that high-demand thicknesses of BeCu sheets are always available for immediate export.
The highest strength of all copper-based alloys. Tensile strength >1380 MPa. Ideal for heavy-duty springs and pressure sensors.
Optimized for thermal conductivity (up to 60% IACS). Preferred for resistance welding tips and plastic mold inserts.
Contains a small amount of lead to enhance machinability for precision Swiss-turning components without sacrificing strength.
One of the primary challenges in utilizing Beryllium Copper Sheets is the heat treatment process. At Sichuan Kepai, we provide not just the material, but the technical expertise for "Age Hardening." Precipitation hardening at 315°C (600°F) for 2-3 hours transforms the material from a formable state to its maximum hardness (up to 45 HRC).
Sustainability Note: We employ closed-loop filtration systems to ensure that any particulates generated during the milling or grinding of our sheets are captured, adhering to ISO 14001:2015 standards. This commitment to environmental stewardship makes us a preferred partner for Fortune 500 companies with strict ESG mandates.
In addition to a high share of the domestic copper alloy market, Kepai has exported to overseas clients with high reputation across Europe, the Americas, and Southeast Asia.
