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 have been using this wire to weld 0.060" Aluminum sheet, and it works really well.MIG Welder, 100% Argon gas, you need to use a Spool gun, and it takes a while to dial it in. You need to practice, but now I can weld corner seams, and butt joints.You need to keep moving, if you stay in one spot it will burn through, but the results are totally acceptable!
