ER4043 Aluminum MIG Welding Wire - 1 lb, 0.035" Diameter (4 Spools) Review

ER4043 - MIG Aluminum Welding Wire - 1 Lb x 0.035" (4 SPOOLS)

Characteristics

ER4043, also known as "AlSi5", is a highly versatile aluminum welding wire widely used in general-purpose applications. With its 5% silicon content, ER4043 exhibits excellent resistance to weld cracking, making it less sensitive than other aluminum alloys. The presence of silicon also helps lower the melting point, enhance the fluidity of the weld puddle, and results in a bright, shiny weld deposit. This welding wire is commonly utilized for welding various grades, including 6061, 6063, 5052, 3004, 3003, and cast alloys such as 356.0, 357.0, 413.0, and 443.0. With a melting range of 1065 °F– 1170 °F and a density of 0.097 lbs/in3, ER4043 ensures reliable performance and optimal post-anodizing gray color.
