Blue Demon ER4043 TIG Welding Rods
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.

I've been using these for a few years and never experienced any issues with them. The price is reasonable, they arrive quickly and overall, I'm very happy with them.Now, I'm not here building rockets or scientific equipment, so my use in fabrication and custom pieces, I would absolutely recommend them.

For my small-time repairs of 7" thin wall ally vacuum pipe/nozzles and other things, these have worked well. If you have 1/16 and 3/32 you can take on a lot of common aluminum repairs.They have a slight smut on them from the drawing process so I'd recommend giving them a good wipe and using a little acetone. They clean up really well. I do this out of habit with ally rods anyhow to avoid contamination screwing up a weld. Remember aluminum in general likes to be clean and tidy for good welding.As far as flow and the actual welding, I have no issues with them.As far as strength and mechanical properties, well it's stronger than the base material I've been working with in many cases. I've used it for reinforcement beads, wear edge build up, and crack repair on a lot of thin wall ally pipe. I've used it on a few other things without anything special to note. Just makes a good solid weld if you do your part.

These rods work great. They weld smoothly and the welds end up with a nice shiny appearance.
