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.

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.

Increases fluidity of the weld puddle and leaves a bright shiny weld deposit.

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.
