Features and Applications
Aluminium wire for welding aluminium alloys with a maximum 2% alloying elements. Including aluminium alloys containing up to 7% Si.
The silicon addition results in improved fluidity (wetting action), making the alloy the preferred choice for welders.
ER 4043 is not sensitive to weld cracking and produces bright, almost smut-free welds. Not recommended for anodizing.
Thicker sections should be preheated to (150°C) prior to welding.
Typically used on many industrial manufacturing sectors, such as automotive, production of mobile equipment and shipbuilding etc.
