ER4043 - MIG Aluminum Welding Wire - 16 Lb x 0.035

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 applicationsLess 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 fewMelting range is 1065 °F - 1170 °F density is 0.097 lbs/in3 and post anodizing color is gray16 Lb of wire per Spool - Available diameters: 0.030 0.035 and 0.045 - Select your choice from the menu.
