Why Are Alloys Used Instead of Pure Metal?
In nature, most metals occur as alloys, as mining deposits typically contain multiple metals. The desired metal must be extracted from other metals and waste materials, after which it is refined, leaving a pure metal. Manufacturers create alloys, which are two or more pure metals combined together, by using heat to blend them together. Both alloys and pure metals have advantages and disadvantages, depending upon their application.

Conductivity refers to the transmission of electrical current and ductility refers to the ability to mold the material into strands. Unfortunately, ductile metals are not ideal for applications where durability is required. Jewelry and industrial equipment manufacturers use alloys to provide a more durable product. For example pure soft gold measures 24 karats, but most rings are 10 karats, meaning they are mixed with silver and copper,
