In the contemporary industrial landscape, the demand for materials that do not compromise between electrical conductivity and mechanical strength has never been higher. Custom Becu (Beryllium Copper) alloys represent the pinnacle of copper-based metallurgy, offering a unique "Information Gain" for engineers seeking to push the boundaries of miniaturization and reliability. As a leading manufacturer and exporter, we provide solutions that address the critical bottlenecks in 5G infrastructure, electric vehicle (EV) power systems, and aerospace instrumentation.
The global beryllium copper market is projected to expand significantly, driven by the rapid adoption of EVs and the burgeoning renewable energy sector. High-performance alloys like C17200 and C17300 are the silent enablers of sub-millisecond switching and ultra-reliable connector interfaces in mission-critical environments.
Unlike standard bronze or brass, BeCu alloys maintain superior conductivity while offering tensile strengths comparable to high-grade alloy steels. This allows for thinner components that carry higher currents without overheating, a fundamental requirement for the next generation of smart grids.
Our manufacturing processes adhere to the strictest ISO 9001:2015 and IATF 16949 standards, ensuring that every batch exported meets global safety and environmental regulations (RoHS/REACH).
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. has rapidly ascended as a high-tech titan in the special copper alloy sector. We specialize in the R&D, production, and international sales of high-conductivity and high-strength free-cutting tellurium copper, beryllium copper, and other innovative alloys.
Our commitment to innovation is backed by a state-of-the-art 29,000 square meter factory floor space, where we transform raw materials into precision-engineered assets for over 1,000 global customers.

Our R&D roadmap focuses on the "Green Metallurgy" initiative. While traditional Beryllium Copper offers unmatched performance, we are pioneering low-beryllium and oxygen-free tellurium copper variants that provide 95% of the performance with 100% environmental compliance. This technological evolution ensures that our clients in the EU and North America stay ahead of tightening environmental mandates.
Optimizing heat-treatment cycles for C17200 to achieve ultimate tensile strengths exceeding 1380 MPa (200 ksi) while maintaining high thermal dissipation.
Enhancing the machinability of BeCu alloys through controlled additions of lead (as in C17300) or sulfur, reducing tool wear by 30% in high-speed CNC environments.
Scaling the production of OFT (Oxygen-Free Tellurium) copper to support the high-power charging (HPC) requirements of the EV industry.
Becu alloys are critical for battery management systems (BMS) and charging connectors. Their resistance to relaxation at elevated temperatures ensures long-term contact reliability.
Utilizing the non-magnetic and anti-sparking properties of BeCu for MRI components and precision surgical tools. Copper's natural antimicrobial properties offer a significant "Information Gain" for hospital environments.
High-reliability connectors for avionics and generators. Our C19160 high strength copper alloy provides the durability needed for extreme atmospheric conditions.
Provides the highest strength of all available copper-beryllium alloys. Tensile strength can exceed 1380 MPa, making it ideal for heavy-duty springs and pressure sensors.
Known for its high electrical conductivity and good fatigue resistance. It is the preferred choice for resistance welding electrodes and high-stress electrical switches.
Offers a combination of high conductivity and excellent machinability. It is widely used in plasma cutting electrodes and power distribution components.
With an independent R&D team and a complete production system, Sichuan Kepai New Materials Co., Ltd. continues to innovate in the development of tellurium copper alloy materials. We participate in the formulation of industry standards, ensuring our products like the High conductivity C51100 phosphor copper and C26000 Brass remain at the forefront of the market.
A: BeCu alloys provide a unique combination of strength (comparable to steel) and high thermal/electrical conductivity. This makes them indispensable for components that must endure high stress while maintaining electrical performance, such as spring contacts and connectors.
