Aluminum welding wire ER4043 is a general-purpose type aluminum welding wire. It 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. It can be used to weld various grades of aluminum.

  • 5% silicon aluminum (AlSi5) filler metal welding wire for MIG welding process.
  • The silicon additions result in improved fluidity (wetting action) to make the alloy a preferred choice by welders. Less sensitive to weld cracking and produces brighter.
  • It can be used to weld various grades of aluminum, 3003, 3004, 5052, 6061, 6063, and casting alloys 43, 355, 356, and 214.

I like the flux core wire. It seems to work well. Low splatter and strong weld. Easy to work with. I would of give 5 stars, but they shipped me the wrong one the first time I ordered.

Being new to aluminum welding, I wasn't sure of what I was ordering. I received what I thought I needed, and it arrived on its' due date. I was waiting for the wire to finish welding an aluminum fender and put my horse trailer back on the road. The wire performed wonderfully
