Premium quality ER4043 Aluminum MIG welding wire 1-Lb spool. Available wire diameters: 0.030" (0.8mm), 0.035" (0.9mm), 0.045" (1.2mm). Shielding gas: Argon or Helium or mix. Specifications and Features: AWS A5.10/ASME SFA A5.10/ER4043. 1-lb weight of welding wire. 4" spool wrapped in moisture-resistant plastic film.

Typical Element Content (wt%) in Product: Si=4.5-6.0; Fe=0.8; Cu=0.3; Mn=0.05; Mg=0.05; Zn=0.1; Ti=0.2; Al=balance. 5% silicon aluminum (AlSi5) in filler metal welding wire. 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.

Applications: General-purpose, all-position aluminum welding wire used to weld various grades of aluminum; it contains silicon additives, which may improve fluidity of the weld pool and also produces a weld less sensitive to cracking; its bright weld finish makes it a popular choice of welders. Recommended for welding 3003, 3004, 5052, 6061, 6063, and casing alloys 43, 355, 356, and 214.
