Union AlSi 10 Cu 4

Solid wire for GMAW of AlCu alloys. Provides higher strength and better ductility than AlSi filler alloys when welding AlCu alloys. Superior resistance to stress corrosion cracking where high-temperature properties are required. Thorough cleaning of the workpiece bevels is necessary prior to welding.

Is a pure aluminium welding wire for joining and surfacing of aluminium materials according to EN ISO 18273. It is a welding consumable with Ti for grain refinement and weldable in all positions.

Solid wire for GMAW of AlCu alloys. Low melting point and excellent penetration characteristics. Provides superior wetting characteristics compared to Union AlCu 6 Mn when welding AlCu alloys, the strength, on the other hand, is lower. Superior resistance to stress corrosion cracking where high-temperature properties are required. The weld metal is not suitable for anodizing for decorative purposes. Thorough cleaning of the workpiece bevels is necessary prior to welding.

Solid wire for GMAW and GTAW of AlMg alloys. The weld metal is resistant to seawater. Base material should be cleaned near the seam. Pre-heating 150°C for plates > 15 mm.
