Zinc (Zn)

Zinc metal ingot - one troy ounce - .9999 bullion   Though credit for its discovery was awarded to German chemist Andreas Sigismund Marggraf for discovering its pure metallic form in 1746, zinc has been used in brass (an alloy of copper and zinc) since about the 10th century BC in the Judea Province and about 300 years later in Ancient Greece. Zinc is a hard, silvery-white, corrosion resistant metal with a relatively low melting point of 787 °F. It is used primarily in the galvanization of iron which is a corrosion resistant zinc plating. Alloys including bronze make up the bulk of its other uses. Pennies in this country have been made with 97.5% zinc with a thin copper coating since 1982. Worldwide annual production is about 13 million tonnes, exceeded only by the other base metals iron, aluminum and copper. Inscribed on our ingots are the chemical symbol (Zn), purity (99.99%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our l
