How do we use zinc and lead?

Zinc is used to galvanize steel, making it stronger and preventing corrosion. It’s used to make things like die-case alloys for the automotive and electrical industries and, when combined with copper makes brass. Zinc is also used to manufacture many things we take for granted in our daily lives, including paints, cosmetics, plastics, batteries, soap, pharmaceuticals and vitamin supplements. Lead is a widely used metal with more than half of global production used to manufacture lead-acid batteries. It’s also used in plumbing, for solder, sound proofing and ammunition. When you add lead to glass, it blocks radiation, so is used in television and computer screens.
