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.
