Metallic glasses or amorphous metals are solid metallic materials, usually made from an alloy of various metals. Metallic glasses are like oxide glasses such as the soda-lime glass used for windows and bottles, but unlike standard glass they also have exceptional electrical conductivity. They are also much tougher and less brittle than oxide glasses and ceramics. Like glass, they soften and flow upon heating. This allows for easy processing, such as by injection molding, in much the same way as polymers. Metallic glasses are fascinating because many of their important properties and behaviour are only now beginning to be understood. Amorphous alloys do not have a specific atomic configuration, grain boundary, crystal segregation and defect. Therefore, an amorphous alloy exhibits a higher corrosion and wear resistance, tensile strength, and fatigue strength than a crystalline alloy with the same composition.

The alloys of boron, silicon, and phosphorous combined with magnetic metals such as iron, cobalt and nickel have high magnetic susceptibility, and high electrical resistance.
