Description

Aluminium wires and rods for welding and brazin. 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 aluminium sheets, for extrusions and castings.

(After anodizing the welding will be of a different colour.)
