Semi-Finished Products & Custom Parts
CuCr1Zr is the most widely used copper alloy for resistance welding electrodes. We supply semi-finished stock or custom-made parts tailored to your specific technical requirements.
The material provides an excellent combination of high electrical and thermal conductivity with good mechanical strength, making it suitable for most standard welding applications.
Available in cold-worked or cold-worked and age-hardened conditions. With our extensive inventory, we offer short lead times and flexible production of custom parts.
Material Variants
WIRBALIT® HF/N/G is available in three variants, each optimized for specific applications:
WIRBALIT® HF
High-strength age-hardened electrode material
Applications: Spot welding electrodes, electrode caps, projection welding electrodes
WIRBALIT® N
Age-hardened electrode material for projection and butt welding
Applications: Projection welding, butt welding, electrode holders
WIRBALIT® G
Age-hardened electrode for roller seam welding
Applications: Seam welding wheels, large diameter electrodes, rings and discs

Available Forms
We supply WIRBALIT® HF/N/G in a wide range of standard and custom forms:
Processing Guidelines
- •Material can be machined in both cold-worked and age-hardened conditions using standard carbide tooling.
- •Age hardening temperature: 450-500°C for 2-4 hours, depending on cross-section.
- •Avoid prolonged exposure to temperatures above 500°C to prevent softening.
- •Cold forming is possible in the solution-annealed condition.
