AMZ4 (ZrCuAINb)
Additive Manufacturing is in our Genes.
When it comes to AM with metals, Heraeus is your reliable partner all along the way. With decades of experience in metal handling and recycling, combined with our thorough expertise in additive manufacturing, we are able to provide you with true peace of mind. Our command of processes, powders and printing enables the highest degree of design freedom for your components.
With high-quality powders, batch consistency and trace-ability, and variable particle size distribution, we can meet even very exacting AM demands.
That’s because we have EXPERTISE TO THE CORE™. Powder Printing

and machinability
Typical PropertiesAMZ4 is a patented zirconium-based bulk metallic glass forming alloy. Metallic glasses are alloys that can be formed into non-crystalline amorphous solids. Their specifi c formulation enables to maintain the disordered (amorphous) structure of the molten state down to room temperature. This is achieved by cooling the melt at fast enough rates, so that the atoms cannot arrange into the ordered confi guration inherent to conventional crystalline alloys. Due to their disordered atomic structure, metallic glasses have remarkable properties. The absence of a crystalline lattice structure and its corresponding defects results in
■ high strength ■ high hardness ■ excellent elastic characteristics ■ good wear resistance ■ good corrosion resistance ■ thermoplastic formability
This unique combination of properties makes metallic glasses suited for high-tech applications in various fi elds such as
■ springs ■ wear resistant gears ■ (micro) mechanical components ■ medical instruments ■ sensors ■ casings of consumer electronics
Heraeus offers this alloy as amorphous powder suitable for thermoplastic forming, injection molding, casting and additive manufacturing (LBM and EBM). Other semi-fi nished products and components are available upon request.
