Key Points. Zinc is used in alloys with copper to create a harder metal known as brass. In galvanization, zinc coats iron by oxidizing to form a protective layer of zinc oxide (ZnO) that protects the iron from rust. Cobalt and nickel are trace elements with properties similar to iron.
An alloy of 75% copper and 25% nickel was traditionally used for the production of nickel coins. However, because of shortage of nickel metal during the war, it was substituted by more available silver and manganese, thus resulting in an alloy of 56% copper, 35% silver and 9% manganese.
copper sulphate is used as an agricultural poison, and water purifier Zinc The alloy brass contains copper and anywhere from 2045% of zinc, depending upon the type of brass. Brass is easy to work and is a good electrical conductor. Substitutes for brass are sometimes preferred
