Alcotec ER4043 3/64 1 lb Aluminium MIG Wire
This aluminium MIG wire carries AWS classification ER4043 and is supplied on a one-pound plastic spool. The wire diameter is 0.047 in and the alloy series is 4043. It is intended for welding aluminium to aluminium of the 4043 grade using 100 percent argon shielding gas. The welding current designation is DCEP.
Suitable for flat, horizontal.
Welders who need a 1 lb spool of ER4043 alloy for the listed positions and the DCEP current type will find this wire matches the specification. Buyers who require a different wire diameter, a different alloy series, a larger spool weight, or a welding process other than MIG (GMAW) should look at other products.
As-welded tensile strength 34 ksi
The as-welded tensile strength is 34 ksi and the as-welded yield strength is 28 ksi when using 100 percent argon. The minimum required yield strength is 10 ksi. This tensile figure is the primary mechanical property that determines whether the wire meets the joint design requirements for the intended aluminium fabrication.
