ELBRODUR® B: Circles/Plates/Rings |
|
|
|
|
ELBRODUR® B (CuCo2Be) is a high-strength age-hardened electrode material having particularly high hardness along with medium electrical conductivity. Used for spot, seam, projection and butt welding. Suitable for high-strength, corrosion-resistant alloyed steels as well as nickel and nickel alloys.
Special grades for bending or extrusion, and for chain welding electrodes on special inquiry.
