amorphous metal An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a high ...

alloy An alloy is a mixture of chemical elements of which at least one is a metal. Unlike chemical compounds with metallic bases, an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity, ductility, ...

s began in 1970. Over the years, many new alloys have been found using the same principles of rapid solidification. Metglas, also known as metallic glass alloys, differ from traditional metals in that they have a non-crystalline structure and possess unique physical and magnetic properties that combine high permeability,

toughness In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing.Amorphous metal transformer An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. The magnetic core of this transformer is made with a ferromagnetic amorphous metal. The typical material (Metglas) is an alloy of iron with bor ...
