CuBe2Pb, also known by the UNS designation C17300, is a high-performance beryllium copper alloy specifically engineered for enhanced machinability. By incorporating a precise amount of lead (Pb), this alloy maintains the legendary strength and conductivity of beryllium copper while allowing for high-speed automated machining. For global procurement teams, finding a factory that masters the delicate balance of metallurgical purity and dimensional stability is critical.
Traditional Beryllium Copper is notoriously difficult to machine. The addition of lead acts as an internal lubricant and chip breaker. This results in reduced tool wear, smoother surface finishes, and significantly faster production cycles. It is the "gold standard" for complex electronic connectors, automotive sensors, and aerospace components where high strength meets intricate geometry.
In the modern "Semantic Search" landscape, users aren't just looking for "copper suppliers." They are searching for high-conductivity, free-cutting alloys that meet RoHS compliance or specific tensile strength thresholds. Our role as a leading manufacturer is to provide the "Information Gain" that helps engineers solve high-heat and high-stress design challenges.
Established in 2017, Sichuan Kepai New Materials Co., Ltd. is a premier high-tech enterprise dedicated to the R&D, production, and global distribution of strategic copper alloys. Spanning 9,000 square meters of advanced manufacturing space, we specialize in high-conductivity oxygen-free copper, silver copper, dispersion copper, and the high-performance CuBe2Pb series.
Our facility is strategically located in the Sichuan Guanghan Industrial Development Zone, integrated into the national 13th Five-Year Plan for emerging new materials. We serve critical industries including New Energy Vehicles (EV), 5G Telecommunications, Laser Cutting, and Aerospace Relays.
Chinese factories like Kepai benefit from a localized ecosystem. From raw material smelting to precision drawing and heat treatment, the entire value chain is optimized for speed. This reduces lead times for global enterprises significantly compared to European or North American counterparts.
We don't just "make" copper; we engineer it. Our research focuses on high-conductivity, easy-to-machine, and high-strength copper alloys. By utilizing vacuum smelting and continuous casting, we ensure oxygen content is kept to an absolute minimum, enhancing the electrical properties of the CuBe2Pb alloy.
Utilizing China's infrastructure and industrial clusters allows us to provide "Information Gain" through cost-optimized manufacturing without sacrificing quality. Our ISO-certified processes ensure that every batch of CuBe2Pb meets international standards like ASTM B196 or EN 12164.
Our team of senior experts continuously explores the boundaries of new copper alloy materials. Through industry-university-research collaboration, Kepai has achieved breakthroughs in high-performance tellurium copper, lead copper, and sulfur copper, reaching international advanced levels.
Our product line ranges from basic oxygen-free copper to high-end beryllium copper and chromium zirconium copper. We focus on providing solutions that reduce production costs while enhancing final product performance and environmental friendliness.
Rooted in Sichuan, we radiate across the globe. By establishing stable customer bases in multiple countries and partnering with internationally renowned enterprises, Kepai is a trusted name in the global materials market.
As 5G and IoT devices shrink, the components within them must become smaller yet more durable. CuBe2Pb is the preferred choice for micro-connectors due to its ability to be machined into ultra-thin walls without losing mechanical integrity.
EV charging systems and battery management systems (BMS) require materials that can handle high currents and resist thermal fatigue. High-performance beryllium copper alloys are increasingly used in EV high-voltage connectors and relays.
Modern factories are shifting toward closed-loop recycling systems. At Kepai, we focus on sustainable development, ensuring our CuBe2Pb production adheres to strict environmental guidelines and promotes industrial upgrading.

CuBe2Pb is vital for bushings, bearings, and non-sparking safety tools. Its high strength-to-weight ratio and resistance to galling under pressure make it indispensable for landing gear components and satellite connectors.
Downhole drilling tools operate in corrosive, high-pressure environments. Beryllium copper alloys provide the necessary hardness and corrosion resistance while allowing for the machining of complex threading required in drill string components.
From pogo pins to spring contacts, CuBe2Pb ensures reliable electrical transmission over millions of cycles. Our material provides the "Memory effect" required for springs that must maintain their shape under constant tension.
C17200 is the standard beryllium copper, while C17300 contains a small percentage of lead (0.2-0.6%). This addition makes C17300 significantly easier to machine on automatic lathes without compromising its physical properties.
We use eddy current conductance instruments and microcomputer-controlled universal testing machines to verify every batch. Chemical composition is tested in-house to ensure it meets international alloy standards.
Yes. CuBe2Pb is age-hardenable. It is typically machined in the "A" (annealed) or "H" (hard) temper and then heat-treated at approximately 315°C to 325°C to achieve maximum hardness and conductivity.
Absolutely. We prioritize sustainable development and ensure our materials meet the highest environmental standards required for export to the EU and North American markets.
Standard stock items can ship within a week, while custom extrusion or specialized drawing orders typically take 3-5 weeks depending on the complexity and volume.




Looking ahead, Sichuan Kepai New Materials Co., Ltd. will continue to uphold its original intention, with even greater enthusiasm and determination, to engage in research and application in the field of new materials, contributing to the development of the new copper alloy materials industry in China and globally.
