Metallurgy is the study of metal. It encompasses the physical and chemical properties of metals found in nature. These natural metals are often called metallic elements. Common metals are gold, iron, copper, aluminum, and silver.

Gold

Gold is often used in jewelry making. It is a soft metal and this malleability makes it ideal for molding and etching jewelry designs.

Historically, gold was used as a monetary substitute and was often used as barter for obtaining goods and services, even in early civilization. It resists oxidation and corrosion more so than other popular metals, making it ideal for use in dentistry and the electronics industry.
