Union AlCu 6 Mn
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.
Union AlMg 5 Mn (solid)
Solid wire for GMAW 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 48
UTP 48 contains 12% Si for welding of aluminium alloyed with copper, silicon, and magnesium. Also excellent for joining dissimilar grades of aluminium. Unique self-lifting slag. Pure white coating outlasts conventional products in moisture resistance. Available in hermetically sealed aluminium tins.
UTP 485
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.
