ER4043 1/8" x 36" Tig Wire 10lb/ bx

It contains silicon additives which result in improved fluidity of the weld pool.

It has a bright weld finished making it a popular choice for welders.

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.

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.

Brazing of 1100 and 3003 can be accomplished with free flowing 4043 composition.

Aluminum filler materials are silicon-aluminum types for welding of 6052 and 6063 types; in some cases, other aluminums are also welded with this type.
