Zinc & alloys

The most important ore is zinc oxide ( ZnO), zinc carbonate ( ZnCO3 )
Used in electric bells and for preparing printing block
Used for making brass

The mechanical properties of these zinc alloys make them attractive substitutes for cast iron and copper alloys in many structural and pressure-tight applications. Because zinc is less costly than copper, these zinc alloys have a distinct cost advantage over copper-base alloys. The ease of machining of zinc and its inherent corrosion resistance give it advantages over cast iron.
