Industrial grade materials optimized for conductivity and strength.
In the current era of "Industrial 4.0," material science acts as the cornerstone of innovation. C18150 (Chromium Zirconium Copper) has emerged as a critical strategic material. Unlike standard copper, C18150 is engineered through precipitation hardening, offering a unique synergy of high electrical conductivity (minimum 80% IACS) and exceptional mechanical strength at elevated temperatures.
As a leading OEM C18150 properties supplier, Sichuan Kepai New Material Co., Ltd. recognizes the shifting demand in the global market. From the rapid expansion of EV charging infrastructure to the precision requirements of 5G telecommunications, C18150 provides the thermal stability that traditional alloys lack.
C18150 maintains a conductivity of 80-90% IACS, making it superior for high-current applications where heat dissipation is critical. Our proprietary cold-working process ensures minimal resistivity loss.
With a softening temperature exceeding 500°C, this alloy retains its hardness and strength in environments where pure copper would fail due to recrystallization.
The addition of Zirconium (Zr) inhibits grain growth at high temperatures, providing a tensile strength of 400-550 MPa depending on the temper (H04 or H08).
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.

Looking ahead, the demand for C18150 properties will be driven by the "Electrification of Everything." Kepai is investing in "Grain Refinement Technology" to further improve the fatigue life of resistance welding electrodes. We are also exploring the integration of C18150 with additive manufacturing (3D Printing) to create complex cooling channels for aerospace applications.
Our commitment to sustainability means we are optimizing our smelting processes to reduce carbon footprints by 20% by 2030, aligning with global green initiative trends.
C18150 contains Zirconium (Zr) in addition to Chromium. This addition significantly improves the alloy's resistance to sticking on galvanized steel during resistance welding and enhances its softening temperature compared to C18200.
Depending on the profile complexity and volume, our standard lead time ranges from 2 to 4 weeks. We maintain a strategic inventory of rods and plates for rapid dispatch.
Yes, every shipment is accompanied by a Mill Test Certificate (MTC) detailing the chemical composition and physical properties (conductivity, hardness, tensile strength) as verified by our internal labs.
Its high conductivity reduces energy loss as heat, while its mechanical strength ensures the longevity of plug contacts through thousands of mating cycles.
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!
