ER4043 MIG Aluminum Welding Wire 1 Lb X 0.035 (6 SPOOLS)

  
ER4043 - MIG Aluminum Welding Wire - 1 Lb X 0.035 (6 SPOOLS). 0.035 - (6 Spools). 12.32 x 9.37 x 2.76 inches. 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. 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. 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. Melting range is 1065 °F- 1170 °F, density is 0.097 lbs/in3 and post anodizing color is gray. 1 Lb of wire per Spool - Available diameters: 0.030", 0.035" and 0.045 - Available Spool Quantities 1, 2, 4 and 6-Pack.
