Union AlSi 10 Cu 4
Rod for GTAW 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.

Union AlSi 5
Rods for GTAW of AlSi containing up to 5% Si. Oxyacetylene welding respectively brazing with suitable fl uxes possible. The weld metal is not suitable for anodizing for decorative purposes. Very fl uid weld pool. Base material should be cleaned near the seam. Pre-heating 150 - 200°C for plates > 15 mm. Do not use for welding hardenable alloys is highly stressed zones.
Union AlSi 7 Mg
Union AlSi 7 Mg is a modified 4010 alloy (alloy 4008) with low levels of impurities, specially designed for joining or repairing 7% Si aluminium cast components like 356.0, A356.0 and A357.0. The mechanical properties can be increased by heat treatment. Thorough cleaning of the workpiece bevels is necessary prior to welding.
