Zinc is a chemical element with the atomic number 30. Zinc is a bluish white, bright, anti – magnetic transition metal.It is slightly less dense than iron and has a hexagonal crystal structure.Zinc is hard and brittle at room temperature, but becomes ductile at 100 to 150°C.When the temperature exceeds 210 °C, the zinc becomes brittle again and can be beaten to break it.The conductivity of zinc is in the middle.It has a relatively low melting and boiling point in all metals.It has the lowest melting point of any transition metal except mercury and cadmium.

Zinc is an irreplaceable and quite important metal in battery manufacturing.Different kinds of low temperature zinc alloys can be formed by adding other elements.Many alloys contain zinc. Brass, for example, is an alloy of zinc and copper.Other metals that can form binary alloys with zinc include aluminum, antimony, silver, tin, magnesium, cobalt, nickel, tellurium, cadmium, lead, titanium and sodium.
