ER4043 .035 X 1 lb Spool MIG Blue Demon Aluminium Welding Wire

Description

ER4043 is a general-purpose type aluminum
welding wire. It is one of the oldest and
most widely used welding and brazing alloys.
This aluminum alloy contains silicon additives,
which result in improved fluidity (wetting action)
of the weld pool and also produces a weld less
sensitive to cracking. Its bright weld finish makes
it a popular choice of welders. ER4043 can be
used to weld various grades of aluminum.
Applications
• Welding filler wire
• Spray and flame metallizing wire
