Commodity Zinc is a brittle, whitish metal used in a wide range of industries, most familiarly as a galvanizing material for steel. Known and used for millennia, it was named "zinc" in the early 1500s by Paracelsus, a Swiss physician and philosopher. The name was derived from "zinke," a German word for "fork tooth," referring to the form zinc often took when smelted.

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 …
