Electrode Material CuCo2Be – CuCo2Be DIN EN 12163/12167
Electrode Material CuCo2Be is a high strength electrode material which, by way of special heat treatment, combines high hardness with good thermal and electrical conductivity. Heating beyond the softening temperature of 500°C significantly reduces the mechanical and physical values.

Example uses
Electrodes for electrical resistance welding (spot, roll seam, projection and butt welding). Electrode Material CuCo2Be is primarily used to weld alloyed, high strength, corrosion-resistant steels.
Machinability
Electrode Material CuCo2Be is machinable similar to pure copper. The formation of built-up edges can be counteracted by increasing the cutting speed.
