Weldcote 4043 Wire – 0.035 in
Weldcote 4043 (commonly referred to as AlSi5) is a 5% silicon aluminum filler metal that is available in Spools or cut lengths for MIG or TIG welding processes.
Features
4043 aluminum filler metal is recommended for welding 3003, 3004, 5052, 6061, 6063 and casting alloys 43, 355, 356 and 214
The melting range is 1065-1170°F with a density of .097 lbs./cu.in
The average tensile strength is 27,000 psi, average yield strength of 18,000 psi and the post anodizing color is gray
4043 aluminum filler metal is one of the oldest and most widely used welding and brazing alloys
The silicon additions result in improved fluidity (wetting action) to make the alloy a preferred choice by welders
