Unlike its counterpart C17200, C17300 Copper Alloy contains a small addition of lead. This minute modification enhances machinability by up to 20%, making it the industry standard for precision CNC turned parts where high strength and complex geometries are required.
In the world of connectors and aerospace components, C17300 provides unparalleled fatigue resistance. It maintains its mechanical integrity under extreme thermal cycles, ensuring that your mission-critical applications never fail due to material stress.
As a leading C17300 copper alloy factory, Sichuan Kepai understands the global shift toward electrification. We supply the materials that power the "5G + EV" infrastructure, bridging the gap between raw metallurgy and future-tech implementation.
Beryllium copper alloys are not just commodities; they are the backbone of high-performance engineering. Our C17300 solutions are integrated into the world's most demanding sectors.
Utilized in bushings, bearings, and landing gear components. Its non-sparking and non-magnetic properties make it essential for cockpit instrumentation and fuel system parts.
From battery connectors to relay contacts, our C17300 provides the necessary conductivity and spring force to maintain connections in high-vibration environments of electric vehicles.
Resistant to hydrogen embrittlement and stress-corrosion cracking, C17300 is ideal for downhole drilling tools where high strength and reliability are non-negotiable.
Precision-machined connectors and heat sinks require the exact balance of free-cutting capabilities and thermal dissipation found in Kepai's optimized C17300 alloys.
Sichuan Kepai New Materials Co., Ltd., established in 2017, is a high-tech enterprise integrating research and development, production, and sales. Currently, the factory covers an area of approximately 9,000 square meters, with an office space of about 1,000 square meters.
The company primarily engages in the production of strategic emerging new materials for the national 13th Five-Year Plan, including special copper alloys such as tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper, while also focusing on the research and development of high-conductivity, easy-to-machine, high-strength copper alloys.
Technological innovation is our core competitiveness. Our R&D team composed of senior industry experts keeps pace with international cutting-edge technology trends. Through industry-university-research collaboration, Kepai has made breakthrough progress in high-performance copper alloys, reaching international advanced levels.
Our product line is rich and diverse, covering oxygen-free copper, nickel tellurium copper, beryllium copper, and chromium zirconium copper. These materials reduce production costs while enhancing durability.

We strictly adhere to RoHS and REACH regulations. Our C17300 alloy is produced with controlled lead content to meet international safety standards while maintaining the required machinability for high-speed automated production.
With our factory located in the Sichuan Guanghan Industrial Development Zone, we offer strategic logistical advantages. We provide localized support to global clients, ensuring short lead times and rapid response to technical queries.
Our commitment to quality is backed by ISO certifications. Each batch of copper alloy undergoes rigorous chemical and physical testing to ensure it meets ASTM B196 and other international benchmarks.
At Sichuan Kepai, we are not just following trends; we are setting them. Our R&D roadmap focuses on the next generation of high-conductivity alloys.
We are actively researching sulfur and tellurium-based high-strength alloys to provide the same machinability as C17300 while anticipating future "Lead-Free" regulatory shifts.
As 6G technology emerges, our copper alloys are being refined to minimize signal attenuation and maximize thermal efficiency at higher GHz ranges.
Developing closed-loop recycling systems for our beryllium copper clients to reduce environmental impact and stabilize material costs in a volatile global market.
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. We look forward to working hand in hand with friends from all walks of life to create a brilliant future together!
