Amorphous Alloys from Heraeus AMLOY

Due to their unique material properties such as high strength combined with high elasticity, corrosion resistance and biocompatibility, amorphous alloys - also known as bulk metallic glasses or amorphous metals - open up completely new possibilities for engineers. Our portfolio includes amorphous alloys based on zirconium. In addition, we are currently researching alloys based on titanium.

Amorphous alloys enable extended product lifetime through corrosion resistance and reduced abrasion. Enabled by the high strength of the material, they also play an important role in miniaturization. Isotropic behavior facilitates the simplification of specifications and product designs.

At Heraeus AMLOY, amorphous alloys are processed by injection molding and 3D printing into near-net-shape components at industrial scale.

Let's work together to drive your sustainable improvements and solve previously unsolved challenges!

AMLOY-ZR01 - Amorphous Alloy: Ideally suited for 3D printing

The zirconium-based alloy AMLOY-ZR01 is ideally suited for processing in 3D printing using the selective laser melting process. Complex geometries and also large component dimensions are realized by an isotropic material behavior. The material is characterized within the AMLOY alloy range by its good ductility. Additive manufacturing of amorphous metals can be used to produce individual components as well as specific surface structures with extraordinary properties.

AMLOY-ZR02 - Amorphous Alloy: The Allrounder Material

The zirconium-based alloy AMLOY-ZR02 is an allrounder material. Whether in additive manufacturing or injection molding, both near-net-shape process technologies enable the production of components in tight tolerances and with high surface qualities. Due to the versatile use of this alloy, large component dimensions can be produced in small to medium series in 3D printing as well as in large series with efficient automation in injection molding.

AMLOY-ZR03 - Amorphous Alloy: Ideally suited for Injection Molding

The zirconium-based alloy AMLOY-ZR03 is ideally suited for injection molding applications due to its very good glass-forming ability and good viscosity in the liquid state. Thanks to our high level of expertise and technical know-how, Heraeus AMLOY is able to produce components in high volumes and within tight tolerances using this alloy on our in-house equipment.
