Aluminum Welding Wire- ER 4047 |
Description :
Aluminum wires and rods for welding and brazing. Good mechanical characteristics, their excellent corrosion resistance and low melting point ensure a very low number of deformations in the origin metal. This material is generally used for brazing
aluminum sheets, for extrusions and castings. (After anodizing the welding will be of a different colour)
