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.

ALLOY 4043 is an Al-5% Si alloy, non-heat treatable.
ALLOY 4043 has a lower melting range than the base metals for which it is commonly used and relieves contraction during weld cooling.
