Union AlMg 5

UTP 49 for welding of aluminium alloyed with manganese and magnesium. Also excellent for joining dissimilar grades of aluminium. Suitable for seawater applications. Unique self-lifting slag. Pure white coating outlasts conventional products in moisture resistance. Available in hermetically sealed aluminium tins.

Rod for GTAW of AlMg alloys containing up to 5% Mg. Seawater-resistant weld metal. Susceptible to stress corrosion cracking if exposed to service temperatures > 65°C. Good colour matching with base metal after anodizing. Thorough cleaning of the workpiece bevels is necessary prior to welding.

UTP 485 is an aluminium stick electrode with 5% Si and a special coating. It is suitable for joining and surfacing AlSi alloys with a Si content of up to 7% and for dissimilar joints of different Al-alloys, such as: 3.3206 AlMgSi 0.5 - 3.2371 G-AlSi 7 Mg 3.3210 AlMgSi 0.7 - 3.2341 G-AlSi 5 Mg 3.2315 AlMgSi 1 - 3.2151 G-AlSi 6 Cu 4 3.3211 AlMg 1 SiCu UTP 485 is suitable for welding plates of wall thicknesses> 2 mm. The soft arc produces a fl at, fi newly-rippled weld seam. Easy slag removal.

Solid wire for GTAW of AlMg alloys. The limited Mg-content of max. 2,8% to obtain intergranular corrosion resistance. Seawater resistant. Recommended for high-temperature applications. For obtaining near-matching coloured joints where anodizing is required.
