Description
- ER4043, commonly referred to as “AlSi5”, has 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 the 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.
- The melting range is 1065 F” 1170 F, density is 0.097 lbs/in3, and the 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.
