C18150 Chromium-Zirconium Copper Alloy - High Strength Electrical Conductivity from China Suppliers and Factory
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.
Compared to pure copper: strength is increased by more than 3 times, while maintaining over 90% conductivity efficiency.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, avoiding cracking or deformation during welding.
Softening temperature ≥ 550℃, maintaining mechanical properties during high-temperature welding (such as point welding of automotive body panels), with a service life 2-3 times longer than that of ordinary copper alloys.
Contains no toxic elements such as beryllium, in line with RoHS standards; cost performance is better than beryllium copper, and the mold manufacturing cost is reduced by 15%-20%.
