A zinc-aluminum alloy coating having desirable ductile properties and a uniform fine grain structure having excellent wettability for a ferrous metal substrate comprises greater than about 25 percent by weight aluminum and zinc, wherein the alloy further includes from about 0.1 to about 1.0 percent by weight of a rare earth alloy for enhancing the wettability of the alloy to the ferrous metal and the balance comprises additional additives and impurities. With alloys having increased concentration of aluminum, the solubility of the rare earth alloy is increased, thereby increasing wettability.
