Optimized C18150 alloys with high thermal conductivity and superior hardness for extreme industrial environments.
Compliance with ASTM B441, RWMA Class 2, and IATF 16949 standards for global automotive and aerospace tiers.
Leveraging China's manufacturing scale to provide cost-effective, high-volume OEM solutions for international markets.
In the landscape of modern material science, C18150 Copper Chromium Zirconium (CuCr1Zr) stands as the definitive choice for applications requiring a synergistic balance of high electrical conductivity and exceptional mechanical strength at elevated temperatures. As a premier OEM C18150 Factory, Sichuan Kepai New Materials Co., Ltd. utilizes advanced precipitation hardening techniques to deliver alloys that outperform standard electrolytic copper in every metric relevant to heavy industry.
C18150 typically consists of 0.5%–1.5% Chromium (Cr) and 0.05%–0.25% Zirconium (Zr), with the balance being Copper (Cu). The magic of this alloy lies in the Solution Heat Treatment and Aging process. During heat treatment, chromium and zirconium atoms precipitate from the copper matrix, creating a dense network of fine particles that block dislocation movement. This results in a material that maintains 80% IACS conductivity while achieving a Rockwell hardness of up to 80 HRB.
From raw material smelting to final CNC machining, our vertical integration ensures 100% traceability and quality control.
Optimized logistics from Sichuan, China, combined with large-scale production, allows us to offer 15-25% better value than Western counterparts.
Our in-house lab can customize alloy ratios for specific high-stress applications, ensuring your OEM requirements are met precisely.
Established in 2017, Sichuan Kepai New Materials has rapidly become a leading C18150 exporter by solving the most common procurement pain point: the trade-off between price and purity. By implementing oxygen-free smelting technologies, we produce Chromium Zirconium Copper with minimal impurities, which directly translates to longer electrode life and reduced downtime for automated welding lines in the EV sector.
Crucial for spot welding electrodes in aluminum and galvanized steel chassis production.
Used in rocket engine combustion chamber liners and high-temperature conductive structural parts.
High-current connectors and switchgear components for photovoltaic and wind energy systems.
Corrosion-resistant conductive pins and underwater communication hardware.
Global enterprises face stringent regulatory landscapes. Our C18150 products are fully compliant with RoHS and REACH directives. We provide comprehensive documentation, including Mill Test Certificates (MTC), SGS reports, and IATF certification, ensuring seamless integration into your local supply chain in Europe, North America, or Southeast Asia.
The copper alloy industry is pivoting toward "Green Manufacturing." This involves the use of recycled high-purity copper scrap and the development of lead-free alternatives. As a forward-thinking C18150 factory, Kepai is investing in carbon-neutral production processes to help our clients meet their Scope 3 emission targets.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength special copper alloys. With a 29,000 sqm facility, we serve over 1000 customers globally, backed by 30+ patents.
