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.
