Amorphous metals combine unique material properties. This makes them predestined for a wide range of innovative high-tech applications in various industries such as aerospace, medical technology, robotics or e-mobility.
Industries and Applications
Unique material properties enable a wide range of applications







Aerospace Industry
Advantages of amorphous metals: Weight reduction and production within tight tolerances
Application: joints, mounting components and turbine blades
High stability and hardness combined with weight savings are key requirements for materials used in the aerospace industry. Lightweight amorphous materials are twice as strong as conventional crystalline, titanium-based alloys and are therefore ideal for aerospace components. The special material properties of amorphous metals also allow the design of components to be optimized. As a result, additional weight savings of up to 20 percent can be achieved compared to equivalent titanium components.
Medical Technology
Advantages of amorphous metals: lower modulus of elasticity and more corrosion-resistant than conventional metals, as well as biocompatible and MRI-compatible
Application: Sharp, durable scalpels and minimally invasive instruments and implants
Materials for medical implants must be biocompatible and corrosion resistant. Pure metals such as platinum, niobium, tantalum or titanium are best suited for this purpose, but in their pure state they are often not hard enough, and in the form of alloys their biocompatibility is reduced at the grain boundaries.
Amorphous metals, on the other hand, have a high strength (>2000 MPa), excellent elasticity and are biocompatible according to ISO 10993-5 and ISO 10993-12 (confirmed by cytotox tests of the University of Graz). In addition, their E-modulus of ~ 85 GPa is similar to the mechanical properties of human bone. They are therefore ideally suited for processing into medical implants.
Automotive Industry
Advantages of amorphous metals: Extremely strong, high hardness, low density and elastic
Application: Stable suspensions and mounting elements, wear-resistant gears and drive components, parts for electric motors, decorative elements and haptic components
Whether it's gears, engine components or rotors: Wherever material can be saved, weight is reduced. This means lower fuel costs and pollutant emissions as well as longer ranges.
Amorphous metals have a low density but are also extremely strong (fatigue strength of 400 N/mm²). With a flexural fatigue strength of 2,500 MPa, they are twice as strong as steel. The special material properties make it possible to change the design of components and make them thinner, more filigree or smaller - without the component losing stability. This not only saves weight, but is also an enormous advantage for parts that are subject to heavy loads and wear quickly, such as suspensions and mounting elements as well as shafts and transmission parts. The high surface quality of the material enables scratch-resistant decorative elements with a pleasant feel for the interior.
Jewelry and watch industry
Advantages of amorphous metals: High surface quality and polish ability
Application: Jewelry and abrasion resistant watch components
Lifestyle products create an emotional connection to their customers. Surfaces of high quality and scratch resistance are therefore essential for lifestyle products such as watches and jewelry.
Consumer Electronics
Advantages of amorphous metals: Shock-absorbing, scratch- and wear-resistant
Application: Break-proof and lighter housings for smartphones as well as more durable hinges and suspension elements, intentional shielding (EMI shielding)
Consumer electronics also require surfaces of high quality and scratch resistance. Amorphous metals guarantee this and also have high elastic properties as well as shock absorption and can be manufactured within tight tolerances (+/-10 µm). Since the material has no tension, amorphous components can also be overmolded with plastic in a further process step. Since the processing of amorphous metals does not involve a phase transformation from liquid to solid, only minimal shrinkage (<0.5%) occurs.
Industrial Applications
Advantages of amorphous metals: high elasticity, low damping, magnetic permeability, corrosion resistance
Application:components for shock transmission, sensors and membranes for speakers, springs and gear parts in robotics
Membranes in sensors have to be highly sensitive in order to deliver exact measured values. At the same time, they must become smaller and smaller in the course of miniaturization - just like springs and gear parts in robotics.
Amorphous metals are extremely elastic and, in the form of membranes, ensure that sensors are more sensitive than with conventional materials. Due to their material properties, they can also be manufactured in very small sizes. In tools that transmit shocks, amorphous metals transmit impulses optimally due to the combination of great hardness and elasticity. Their resistance to corrosion and wear ensures a longer service life for components that are exposed to high abrasion.
Music Instruments

Advantages of amorphous metals: high strength, high elasticity, anti-allergic
Application: guitar bridges, mouthpieces for wind instruments
Whether it is the bridge on a stringed instrument or the mouthpiece on a wind instrument: the optimal sound transmission is decisive for a musical instrument. Due to their elasticity, amorphous metals transmit the stroke of a tone more directly and last longer. This leads to a better sound transmission overall.
The high strength of amorphous metals also enables completely new designs. For example, bionic structures can be created in additive manufacturing to further optimize the sound and realize individual designs. Furthermore, the components do not have to be chrome-plated or otherwise coated in a further step, as the material itself is anti-allergic.
This is the sound of our guitar with 3D-printed bridge made of amorphous metal
Our heart beats for amorphous metals! That's why Heraeus AMLOY has recorded the song "Amorphous" - a hymn on and about amorphous metals, played on our guitar with a 3D-printed amorphous bridge. We developed it together with guitar maker Nik Huber. Due to their elasticity, amorphous metals transfer vibrations very well and thus improve the sound of the instrument. Have fun listening to it!
