C18150 Chromium-Zirconium Copper Alloy Suppliers and Factory in China - High Conductivity and Strength
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, and is widely used as a substitute for materials such as beryllium copper, becoming a core material in fields such as welding, molds, and aerospace.
Core features and technical advantages:
1. Outstanding electrical and 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.
2. High strength and wear resistance, crack 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, avoiding cracking or deformation during welding.
3. Resistance to high-temperature softening and stability
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.
4. Environmental friendliness and cost advantages
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%.
