WIRBALIT® L
CuAg0.10P – 2.1211
Silver-bearing copper alloy with improved softening resistance and excellent electrical conductivity. Ideal for applications requiring high conductivity with enhanced temperature stability.
Semi-Finished Products & Custom Parts
WIRBALIT® L is a silver-bearing copper alloy that offers excellent electrical conductivity combined with improved softening resistance compared to pure copper. The addition of silver and phosphorus enhances the material's performance at elevated temperatures.
This material is particularly suited for applications where maximum electrical conductivity is required alongside moderate strength and improved thermal stability.
We supply semi-finished stock or custom-made parts tailored to your specific technical requirements with short lead times.
