Common reasons for use Corrosive resistant, Galvanization, batteries, acts as an anode, Zinc disc attached to a ship's iron rudder will slowly corrode alloys. Zinc is a vital nutrient to humans. 24th most common element in the planet's crust and yet Zinc is the fourth most common metal in use. The non-magnetic character of zinc and its lack of color in solution delayed discovery of its importance to biochemistry and nutrition. The Importance to the human body was unknown until the early 20th century.
