Refractory Metals

Known for their exceptionally high melting temperatures and extreme physical characteristics refractory metals play a fundamental role in a wide variety of applications. Dense, mechanically resistant to high temperatures and conductive they are a keystone of modern technology.

We have developed and manufacture traditional and novel materials and components for resistance welding with exceptional properties.

Areas of application:

Precious Alloys

Ancient as metallurgy itself, extremely resistant to corrosion and with a wide variety of industrial applications precious metals have accompanied mankind through its progress and evolution.

Due to the possibility to manufacture very fine grained and nano-crystalline alloys of high purity metals and alloys, EPoS’ technology, can drastically improve the scratch proof ability and hardness of precious alloys, without additional surface treatments or with a reduction in alloying elements, making precious alloys even more precious.

Applications:

Watch Bezels
Balance wheels
Watch Gears
Blanks for jewelry and watchmaking
Rings
Electrical contacts/switches
Composites for thermal management
Special tools/electrodes

Hardnesses of over 280 HV have been obtained in 18K3N gold, high resolution SEM images on the left of sub-micron precipitates in nano-crystalline gold sintered by EPoS without heat treatment or addition of alloying elements.

Metal Magnets

This completely new class of magnets unlocks freedom of design and ruggedness in applications such as high-speed spindles without sleeves, rugged electric motors, sensors in vibration-heavy environments and delicate or mission-critical applications needing higher reliability. Metal magnets are composites of NdFeB and common metals that combine the best of both worlds: mechanical ruggedness and hard magnetic properties.

Our first grade, an isotropic Titanium based Metal Magnet TiMM4 H, brings together the strength, toughness and corrosion resistance of titanium with the coercivity of NdFeB.

Features:
- Tensile strength: 300 MPa (43.5 kpsi)
- Outstanding impact resistance
- Superior corrosion resistance to coated NdFeB
- High coercivity: 1788 kA/m @ 20°C
