Amorphous metals, also known as metallic glasses, are a type of alloy with a disordered atomic-scale structure, as opposed to the regular, ordered structure of traditional crystalline metals. They are made by rapidly cooling molten metal, which prevents its atoms from arranging into a regular pattern. This disordered structure gives amorphous metals unique properties, such as higher strength, higher corrosion resistance, higher electrical and thermal conductivity, and improved toughness.
