Aluminium ER4043 MIG Wire 15kg spool

ER4043 is one of the oldest and most widely used welding and brazing alloys. 4043 can be classified as a general purpose type filler alloy. The silicon additions result in improved fluidity (wetting action) to make the alloy a preferred choice by welders. The alloy is less sensitive to weld cracking and produces brighter, almost smut-free welds.
