Explore our high-conductivity and high-strength industrial copper solutions tailored for global OEMs
C172 Beryllium Copper (UNS C17200) stands as the pinnacle of copper-based alloys, renowned for its exceptional combination of mechanical strength, electrical conductivity, corrosion resistance, and anti-galling characteristics. Often designated as the premier age-hardening copper alloy, C17200 possesses mechanical properties comparable to high-strength steels while maintaining the excellent thermal and electrical conductivity of premium copper. This makes it an indispensable material in high-stress, highly conductive applications.
Historically, the procurement of high-grade copper alloys was dominated by a handful of Western mills. However, as global supply chains evolve, modern enterprises require partners capable of combining rapid production cycles, stringent quality control, and cost-effective logistics. Sichuan Kepai New Material Co., Ltd. has risen as a key player in this metallurgical shift, providing advanced OEM manufacturing and global exporting services that align with China's Factory 4.0 paradigms. By employing state-of-the-art continuous casting, precision extrusion, and advanced testing facilities, Sichuan Kepai ensures that each batch of C172 Beryllium Copper meets international standards (such as ASTM B194, ASTM B196, and SAE J461) while offering considerable cost efficiency.
C172 Beryllium Copper undergoes precipitation hardening (age hardening), reaching tensile strengths up to 1400 MPa and hardness up to 45 HRC, outperforming standard brass and bronze alloys.
Maintains an electrical conductivity rating of 22% to 30% IACS (International Annealed Copper Standard), making it the primary choice for electrical connectors and spring contacts.
Excellent resistance to metal fatigue and stress relaxation ensures prolonged cycle life in dynamic mechanical components like switch contacts, diaphragms, and bellows.
Engineering the future of metal alloys through sustainable, high-efficiency manufacturing systems
Sustainable development is at the heart of modern metallurgy. At Sichuan Kepai, we recognize that the extraction and processing of copper and beryllium must be handled with utmost environmental responsibility. Located in the western area of the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108, our facility boasts a superior geographical location and convenient transportation. This strategic hub minimizes logistics emissions while allowing us to tap into Sichuan's rich clean energy reserves, particularly hydroelectric power, which substantially reduces the carbon footprint of our smelting and manufacturing processes.
Since our establishment in 2017, Kepai has adhered to the business philosophy of "innovation-driven development, quality wins the market." We are committed to providing customers with the highest quality high-end copper alloy materials, promoting industrial upgrading and sustainable development.

In practice, the success of C172 Beryllium Copper relies on its dynamic behavior within specific environments. Industrial designers and procurement managers look for exporters who comprehend these localized engineering demands:
Subsea Oil & Gas Drilling: Beryllium copper is widely utilized in drilling equipment, instrument housings, and valve components. Sourcing companies require C17200 because it stands up to highly corrosive environments containing H2S and chlorides, avoiding hydrogen embrittlement while retaining high mechanical strength without generating sparks in explosive gas environments.
Semiconductor Inspection Systems: Precision test probes and contact springs are crucial components of semiconductor testing. Exporters must provide ultra-fine wires or thin foils of C17200 that exhibit minimal fatigue over millions of cycles, ensuring stable electrical contact resistance and preventing measurement drifts.
Automotive Heavy-Duty Relays & Switchgear: With the push toward heavy-duty commercial EVs and hybrid powertrains, electronic contactors must withstand extreme vibrational stress and high switching currents. Sourcing organizations prioritize C172 Beryllium Copper because of its low stress relaxation behavior at elevated operating temperatures (exceeding 150°C).
