Aluminium Tig Wire 4043

ER4043 TIG filler wire is one of the most widely used and versatile aluminum-silicon welding rods designed for Gas Tungsten Arc Welding (GTAW / TIG).
Classified under AWS A5.10 as ER4043, this filler metal is alloyed with 5% silicon, which drastically increases puddle fluidity and reduces weld cracking.

Core Product Features
High Weld Fluidity: The 5% silicon addition lowers the melting point of the alloy and creates a highly fluid weld pool, making it exceptionally easy for operators to control.
Elite Crack Resistance: Its fluid chemistry drastically reduces solidification shrinkage, virtually eliminating hot cracking in highly constrained joints.
Bright, Clean Finishes: Produces bright, aesthetically clean, and finely rippled weld beads with exceptionally low soot or discoloration.
Anodizing Consideration: While highly weldable, the silicon content causes the weld bead to turn a distinct dark grey color if the component undergoes post-weld anodising processes.
