Product Description

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.

Core Features & Technical Advantages

Electrical & Thermal Conductivity

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.

High Strength & Wear Resistance

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.

High-Temperature Softening Resistance

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.

Eco-Friendliness & Cost Efficiency

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%.
