Round bars Ø 6 - 80 0/- 0,2 drawn
Round bars Ø 85 - 91 0/+1 pressed
Round bars Ø 100 - 200 0/+3 pressed
Example uses
Point and rolled seam electrodes for welding low carbon steel sheets (C < 0.3%).
Machinability
Electrode Material CuCrZr is machinable similar to pure copper. The formation of built-up edges can be counteracted by increasing the cutting speed.
