Why SVS
Key Features
Advantages of Copper-Chromium-Zirconium Alloy
High Mechanical Strength
This alloy withstands mechanical loads and wear even under continuous stress and achieves significantly higher strength than pure copper.
Excellent Conductivity
CuCr1Zr delivers nearly the same electrical and thermal conductivity as pure copper, but with superior mechanical strength.
High Temperature Resistance
The material retains its mechanical properties at elevated operating temperatures and shows a high softening temperature.
Applications
Applications
This copper alloy is used in resistance welding systems for electrode caps, special-purpose electrodes, holders, and shanks, ensuring optimal current and force transmission. Its high thermal conductivity allows efficient heat transfer the welding gun's cooling system.
Other applications include current-carrying tools and molded components directly integrated into welding processes, such as welding wheels, seam welding electrodes, flat electrodes, and other conductive elements.
