- noun a metal made from a compound of two or more metallic elements, e.g. brass
- A mixture of two or more elements, one of which must be a metal, to form a macroscopically homogeneous metallic product. Alloys may be solids or liquids, and are usually created to better adapt the constituents for a particular purpose. Alloys are used extensively in electronics. For example, niobium alloys are used as low temperature superconductors.
