Product Description

ER4043 ALUMINUM ALLOY WELDING WIRE is used in MIG processes for all 4000 & 5000 series aluminum materials. It is the most popular general-purpose aluminum MIG wire.

The 4043 has a low melting point and high fluidity which allows the weld to flow better, increases penetration and reduces sensitivity to weld cracking. The 4043 also makes brighter-looking MIG welds because it does not contain magnesium.

Shielding gas required usually 100% Argon

Available in 4" and 8" Spools.
