GEMET 811

IDENTIFICATION
Gemet 811, ENiCu7

CLASSIFICATION
AWS/SFA 5.11 ENiCu7
DIN 1736 EL-NiCu30Mn (2.4366)

DESCRIPTION
Basic coated electrode suitable for joining and surfacing of Nickel Copper - clad steels. The welds are of X-ray / radiographic quality.
The electrode can be used in all positions and has excellent striking and restriking properties. The Fe content in the weld metal is very low. Hence, for overlay applications, it is an ideal electrode.
