Zinc ingots are considered to be pure zinc, which, of course, contains impurities, but the purity zinc ingots should be at least 90%. Zinc ingots fall into four grades by their chemical composition: Zinc 99.995, Zinc 99.99, Zinc 99.95 , Zinc 99.5and Zinc 98.7. Zinc ingots are mainly used in die cast alloy, batteries, printing and dyeing, medicine, rubber, chemical engineering and many other industries. Alloys of Zinc and other metals are widely used in electroplating, coat spraying and other applications.
