What Is a Pure Metal? - Reference

04/08/2015  A pure metal is a substance that contains atoms of only one type of metallic element, such as aluminum, gold, copper, lead or zinc. Most metals very rarely, if ever, appear in their pure form in nature and instead must be extracted from a metal ore. Many metals have very useful properties, such as being good conductors of electricity. However, the majority of metals are too soft and malleable ...

As a pure metal, gold bends and stretches so easily that it would quickly pull out of shape if it were formed into a ring and worn on the finger. Jewelry manufacturers alloy pure gold with silver, copper or zinc to improve the metal's durability and rigidity. The gold contributes its color and ...
