The major uses of zinc metal are in galvanizing iron and steel against corrosion and in making brasses and alloys for die-casting.Zinc itself forms an impervious coating of its oxide on exposure to the atmosphere, and hence the metal is more resistant to ordinary atmospheres than iron and corrodes at a much lower rate. In addition, because …Web
