The Zinc
One of the main applications of zinc is deposited on steels to protect them from corrosion: it is galvanization, the products of which are used in the automobile, household appliances and even industrial equipment. Brass is prepared with copper and zinc. Some bronzes also contain zinc.
Some coins are minted in zinc: this was the case during the Second World War. The roofs are sometimes covered with zinc. This metal also has healing and anti-inflammatory properties.
