C18150 chromium-zirconium copper (chemical formula CuCrZr) is a copper-based alloy reinforced with chromium (0.1%-1.5%) and zirconium (0.02%-0.6%).
It possesses high electrical conductivity, high strength, and resistance to high-temperature softening. It is widely used as a substitute for materials such as beryllium copper, serving as a core material in welding, molds, and aerospace applications.
The conductivity rate reaches 75%-85% IACS, and the thermal conductivity is approximately 320W/m·K. This ensures efficient current transmission and heat dissipation, suitable for high-power welding and precision electronic components.
Hardness range HRB 78-88 (HV 160-185), tensile strength up to 640MPa, excellent fatigue resistance, electrode loss rate reduced by 30%.
After vacuum melting and aging treatment, the microstructure is dense, effectively avoiding cracking or deformation during welding.
Softening temperature ≥ 550℃, maintaining mechanical properties during high-temperature welding (such as point welding of automotive body panels).
Delivers a service life 2-3 times longer than that of ordinary copper alloys.
Contains no toxic elements such as beryllium, aligning perfectly with RoHS standards.
Cost performance is better than beryllium copper, and the mold manufacturing cost is reduced by 15%-20%.
