ER4043 - WIRE - MIG (GMAW) – ALUMINUM

AWS A5.10


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

 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.

Melting range is 1065 °F– 1170 °F, density is 0.097 lbs/in3 and 

post anodizing color is gray.
