Material Behaviour
Key Material Properties
Corrosion Resistance
Finely dispersed chromium and zirconium phases improve wear and corrosion resistance. This makes CuCrZr a durable material for demanding operating conditions.
Thermal Stability
Precipitation hardening ensures that CuCrZr retains its strength and dimensional stability under continuous loads up to approximately 300 °C. The alloy is particularly suitable for thermally stressed components such as welding electrodes or high-current contacts.
Thermal Conductivity
CuCrZr achieves a thermal conductivity of 300 to 340 W/m·K at a tensile strength of 450 to 600 MPa. This makes the material suitable for applications requiring both efficient heat dissipation and mechanical strength.
Fields of Application
Examples of Use
This copper alloy is used in resistance welding systems for electrode caps, seam welding wheels, special electrodes, electrode holders and shanks. The alloy is also used in welding blocks for wire mesh production. It ensures reliable transmission of current and force. Its high thermal conductivity enables efficient heat dissipation into the cooling system of the welding gun.
In tool and mold making, it is particularly suitable for components exposed to thermal cycling and fluctuating mechanical loads, including mold inserts, cores, slides and EDM electrodes.
