ALUMINIUM TIG WIRE ER4043 (ALSI-5) - 1.6MM (5KG) IN SOUTH AFRICA

ER4043 aluminum filler materials are silicon-aluminum types for welding of 6052 and 6063 types, in some cases, other aluminium metals are also welded with this type. Brazing of 1100 and 3003 can be accomplished with free flowing 4043 composition. Welding Filler Wire The proper choice of aluminum filler metal mainly depends on the base metal properties to be achieved and welding technique. Post weld cracking, corrosion resistance and behavior under elevated temperature also need to be taken into consideration. Cracking usually can be minimized by choosing a filler metal alloy of higher alloy content then the base metal.
