DIN EN ISO 18273:
S AI 4047A-Al Si 12A
 

DESCRIPTION

Aluminium wires and rods for welding and brazing.
Good mechanical characteristics: its excellent corrosion resistance and low melting point ensure a very low number of deformations in the parent metal. This material is generally used for brazing aluminium sheets, for extrusions and castings.
(After anodizing the welding will be of a different colour)
