Zinc is Used as an Alloy: Zinc is mixed with copper (brass) and other metals to form material commonly used in vehicles and other appliances. It is also used in the production of zinc oxide (the most important zinc chemical by volume of production), which is used as a protective skin ointment in rubber manufacture.

Zinc metallurgy is the technology that extracts zinc metal from zin-bearing materials. The humankind started using the copper alloy containing zinc long ago. In ancient China, this type of copper alloy had a specific name "tou shi," but it was at a much later time that zinc elementary substance was separated. China was the first country to ...

The history of gold begins in antiquity. Bits of gold were found in Spanish caves that were used by Paleolithic people around 40,000 B.C. Gold is the "child of Zeus," wrote the Greek poet Pindar. The Romans called the yellow metal aurum ("shining dawn"). Gold is the first element and first metal mentioned in the Bible, where it appears in more than 400 references.

• Addition of zinc to copper increases in strength because zinc enters into solid solution in the copper. • Unusual feature : ductility also increases with dissolved zinc content, reaches a maximum ductility value at a zinc content of 30% • Zinc in cheaper than copper, so brasses are more economical than pure copper.
