Sold in 16 pound spools, .045" PowerWeld ER4043 is a popular choice for welders due to its bright weld finish and is one of the oldest and most widely used aluminum welding and brazing alloys.
ER4043 contains silicon additives which provide improved fluidity (wetting action) of the weld pool while also producing a weld that is less sensitive to cracking.
PowerWeld ER4043 aluminum welding wire is triple degreased to provide the highest degree of cleanliness and luster. The PowerWeld "shaved finish" produces absolute uniformity in diameter along with excellent surface smoothness, ensuring uninterrupted feeding in both automatic and semi-automatic welding operations.
PowerWeld also employs unique cleaning methods to remove all traces of oxides, lubricants and acids and packages each spool to maintain its cleanliness, preventing contamination.
