The metals are opaque, lustrous elements which are excellent heat and electricity conductors. Most of the metals are maleable and ductile, and they are usually denser than the other elements. Metals are used in Transportation, Aerospace , Computers and other electronic devices that require conductors, Communications including satellites that depend on a tough but light metal shell, Food processing and preservation, Construction, Biomedical applications, Electrical power production and distribution, Farming, Household etc.
An alloy is a mixture of metals or metals and one or more other elements together. For example, the combination of the metallic elements gold and copper produces red gold, gold and silver creates white gold, and silver produces sterling silver in combination with copper. Mixed with non-metallic carbon or silicon, the elemental iron creates alloys called steel or silicon steel. The resulting mixture forms a material that often varies from the properties of pure metals, such as increased strength or hardness.
