ER4043Commonly referred to as AlSi5", has a 5% silicon and is the oldest and one of the most widely used aluminum welding wires for general purpose applications.. Shielding Gas RequiredUsually 100% Argon, Helium or mix.. Excellent Welding PerformanceThe silicon additions result in improved fluidity to make the alloy a preferred choice by welders. Less sensitive to weld cracking and produces brighter.. Multiple UsageWelding Wire ER4043 can use where base metal require thermal treatment. It also can be used on weld forge and casting materials.. ApplicationsIt can be used to weld various grades of aluminum, 3003, 3004, 5052, 6061, 6063, and casing alloys 43, 355, 356, and 214..
