CLASSIFICATION
| AWS A5.6: ~ECu | ISO 17777: E Cu 1893 (CuMn2) |
DESCRIPTION AND APPLICATION
Copper base electrode with coating for welding various grades of pure copper.
Also suitable for joining dissimilar metals and for surface restoration.
The weld is dense, free of porosity, and has tensile strength comparable to most commercial copper grades.
Used for connecting electrical copper electrodes in furnaces, as well as for copper-to-steel connections in electrically heated drive systems.
