4043A/4943
Alloy Type: A5.10, ALUMINUM AND ALUMINUM ALLOY Electrodes and Rods
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.
Typical Applications: automotive frames, aerospace hardware, bicycles, concrete forms, furniture
