C18150 Chromium Zirconium Copper is a superior copper-based alloy designed for applications requiring a combination of high electrical conductivity and exceptional mechanical strength at elevated temperatures. Unlike standard copper, C18150 undergoes precipitation hardening, where chromium and zirconium form fine particles within the copper matrix, effectively blocking dislocation movement without significantly impeding electron flow.
As a leading Custom C18150 CuCrZr copper manufacturer, Sichuan Kepai provides materials that exceed standard specifications. Our C18150 alloys maintain their hardness and strength up to 500°C, making them the industry standard for resistance welding electrodes and heat exchangers.

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 free cutting tellurium copper and other special copper alloys.
Our facility in Sichuan manages everything from vacuum melting and continuous casting to precision extrusion and heat treatment. This control over the entire supply chain ensures consistent CuCrZr copper alloy quality and reduces lead times for global orders.
Leveraging China's industrial ecosystem, we provide high-performance materials at competitive price points. By optimizing energy consumption and using advanced automation, we pass the savings directly to our international procurement partners.
With an independent R&D team, we don't just follow standards; we set them. Our oxygen-free tellurium copper and optimized C18150 alloys are designed for next-generation EV charging and aerospace demands.
From the depths of the ocean to the vacuum of space, our alloys perform where others fail.
C18150 is critical for resistance welding electrodes in automated car body production lines. Its resistance to mushrooming (electrode tip deformation) ensures millions of high-quality spots welds without downtime.
Used in rocket engine combustion chambers and structural components where thermal conductivity must be matched with extreme heat resistance to prevent structural failure during re-entry or high-velocity flight.
High-speed connectors and 5G base station components rely on the alloy's stability and signal integrity. It provides the necessary spring force while maintaining high conductivity.
For global enterprises, procurement isn't just about price—it's about risk management and regulatory adherence. Sichuan Kepai understands the complexities of international trade.
The transition to Industry 4.0 requires materials that can withstand higher cycles in automated welding. Furthermore, the global drive for green energy is pushing the demand for high-purity copper alloys in photovoltaic inverters and wind turbine generators.
Expert insights into C18150 CuCrZr Copper Alloy procurement and application.
While both are Chromium Coppers, C18150 contains an additional amount of Zirconium (0.05-0.25%). This addition enhances the resistance to softening at high temperatures and improves the alloy's performance in high-stress applications like continuous casting molds.
Yes. As a custom manufacturer, we can produce rods, bars, plates, and wire to your specific tolerances. Our precision extrusion and CNC machining capabilities allow us to deliver semi-finished or finished components.
We use eddy current testing and bridge methods to verify conductivity across every batch. Our vacuum induction melting process minimizes impurities like oxygen and phosphorus that typically degrade conductivity.
Standard sizes are usually in stock and can ship within 7 days. Custom alloy formulations or specific heat treatments typically require 3-5 weeks depending on the order volume.
