In the landscape of high-performance metallurgy, C18150 (Chromium Zirconium Copper) stands as the gold standard for applications requiring a synergistic blend of high electrical conductivity and superior mechanical strength at elevated temperatures. As a premier manufacturer and supplier, Sichuan Kepai New Material Co., Ltd. specializes in unlocking the full potential of this RWMA Class 2 alloy through advanced smelting and heat treatment protocols.
Unlike standard copper, C18150 maintains its hardness up to 500°C, making it indispensable for resistance welding electrodes.
Achieving over 80% IACS conductivity, C18150 ensures minimal energy loss in high-current industrial connectors.
The addition of Zirconium (Zr) creates a protective lattice structure that resists surface degradation in harsh environments.
To provide true Information Gain for procurement officers and engineers, it is vital to understand that C18150 is not just a material—it is a result of precision cooling and precipitation hardening. Our technical roadmap involves the controlled aging of Chromium and Zirconium within the copper matrix to prevent grain growth, a common failure point in inferior alloys.
| Property Class | Metric Value | Industrial Application |
|---|---|---|
| Electrical Conductivity | ≥ 80% IACS | EV Charging Ports, Switchgears |
| Thermal Conductivity | 320 W/m·K | Heat Sinks, Injection Molds |
| Hardness (HRB) | 75 - 85 HRB | Resistance Welding Electrodes |
| Softening Temperature | 500°C | Aerospace Engine Components |
Looking toward the future, Sichuan Kepai is developing Nanostructured C18150 variants. By refining grain size to the sub-micron level, we are pushing the tensile strength limits beyond 600 MPa while maintaining the 80% IACS conductivity threshold—a critical advancement for the next generation of semiconductor testing and high-speed rail electrification.
