Alloy 4043 is one of the oldest and most widely used welding and brazing alloys. AL4043 can be classed as a general purpose type filler alloy. Due to the addition to silicon alloy 4043 results in improved fluidity (wetting action) to make alloy 4043 the preferred choice by welders. Alloy 4043 is less sensitive to weld cracking and brighter and almost smut free welds.
