Featuring High Grade, Special High Grade, Mil Spec, MIL-A 1800L Zinc, and Zinc Sheet in a variety of forms

Centuries before it was identified as an element, zinc was used to make brass (an alloy of zinc and copper) and for medicinal purposes. Metallic zinc and zinc oxide were produced in India somewhere between the 11th and 14th centuries and in China in the 17th century, although the discovery of pure metallic zinc is credited to the German chemist Andreas Marggraf, who isolated the element in 1746. In modern times, Zinc is the 4th most widely consumed metal in the world after aluminum, iron, and copper.

The key property of Zinc, in its various uses, is the relatively slow and predictable rate of corrosion of Zinc compared to steel. As a result, Zinc’s most important uses is in galvanizing, the process of covering steel with a layer of Zinc for protection from corrosion. This is commonly used to protect roofing sheets, girders, nails, ladders, and buckets, and can be achieved by dipping the item in the molten metal or by electrolytic plating. Zinc and Zinc alloys are also used extensively to produce die-casting alloys where they compete fiercely with aluminum. Zinc sheet has many uses, including the cases for dry-cell batteries and the construction industry.
