ER4043 aluminium MIG wire

This ER4043 aluminium MIG wire is supplied on a 1 lb plastic spool for MIG welding (GMAW). It carries AWS classification ER4043 and is intended for aluminium-to-aluminium work. The wire diameter is 0.035 in and the spool weight is 1 lb.

Suitable for flat, horizontal.

This wire suits welders joining 4043 grade aluminium using DCEP current with 100 percent argon shielding gas. It is not for buyers who need a different wire diameter, a different alloy series, or a spool weight other than 1 lb.

Tensile strength 34 ksi and yield strength 28 ksi

As-welded tensile strength is 34 ksi and yield strength is 28 ksi with 100 percent argon. These figures determine whether the mechanical properties match the joint requirements for the application.
