Using Amorphous Metals, also known as Bulk Metallic Glasses (BMGs), Amorphology casts high-resolution net-shape parts, including gears and gear components. Cast amorphous parts display high hardness and wear resistance, are able to operate in un-lubricated environments, exhibit high surface finishes, and are corrosion-resistant. In particular, the casting of BMGs excels for small parts, including small components, or gears with complex geometries.
