PURPOSE:To obtain molten flux for 40 to 80% aluminum-zinc having corrosion resistance more excellent than that of the existing galvanizing in a seashore district and furthermore simply capable of plating on a large sized structural body as for molten flux for hot dip aluminum-zinc plating for a steel material, more specifically, as. flux to be floated on the above plating bath. CONSTITUTION:A molten flux composition for hot dip 40 to 80% aluminum-zinc alloy plating constituted of the fluorides 1 alkali metals including aluminum and the chlorides of alkaline-earth metals and a composition furthermore incorporated with one or >=two kinds among the chlorides alkali metals such as lithium, sodium and potassium are used.
