CHARACTERISTICS :
ER 4043 is a general-purpose type aluminum welding wire. It is one of the oldest and most widely used welding and brazing alloys. This aluminum alloys 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. ER 4043 can be used to weld various grades of aluminum.
APPLICATION :
For welding 6xxx alloys and most casting alloys automotive components such as frame and drive shafts bicycle frames
