Metals and alloys

Definition

Metals and alloys are materials that are typically hard, malleable, and have good electrical and thermal conductivity. Alloys are made by melting two or more elements together, at least one of them a metal. They have properties that improve those of the constituent elements, such greater strength or resistance to corrosion.
