Specification Brand : SÜA BulletPoint1 : ER4043, commonly referred to as “AlSi5", has a 5% silicon and is the oldest and one of the most widely used aluminum welding wires for general purpose applications BulletPoint2 : Less sensitive to weld cracking than other aluminum alloys and the 5% silicon content lowers the melting point, increases fluidity of the weld puddle and leaves a bright shiny weld deposit. BulletPoint3 : ER4043 is commonly used for welding grades 6061, 6063, 5052, 3004, 3003 and cast alloys 356.0, 357.0, 413.0, and 443.0 to name just a few BulletPoint4 : Melting range is 1065 °F - 1170 °F, density is 0.097 lbs/in3 and post anodizing color is gray BulletPoint5 : 16 Lb of wire per Spool - Available diameters: 0.030", 0.035" and 0.045" - Select your choice from the menu.
