Nexalloy - Model ER4043A/4943 -Aluminum Alternative Welding Alloy Wire

Nexalloy 4043A/4943 is an alternative alloy to 4043 with 25% higher Ultimate Tensile Strength (UTS) and 50% higher yield strength in the as welded condition. Similar to 4043 it possesses moderate to high strength (35 ksi typical), low melting temperature and high fluidity, low ductility, formability and lower toughness as well as moderate electrical and thermal conductivity. 4043A/4943 may be used to weld 1XXX, 3XXX, 5XXX with less than 3.0% Mg. Common applications include automotive frames, aerospace hardware, bicycles, concrete forms and furniture.
