ASTM B393 Niobium Foil
Niobium: Gleaming in every color.
In actual fact, niobium, like all other metals, is gray. However, by applying a passifying oxide layer, we allow our metal to gleam in a beautiful array of colors. But niobium is not just pretty to look at. Like tantalum, it is resistant against many chemicals and can be easily formed even at low temperatures.
Niobium is special because this high level of resistance is achieved at a relatively low weight. We use this material to manufacture coin inserts of all colors, corrosion-resistant evaporation boats for use in coating technology, and dimensionally stable crucibles for diamond growth. Thanks to its high level of biocompatibility, niobium is also used as a material for implants. Thanks to its high transition temperature, niobium is the perfect material for superconducting cables and magnets.
You can rely on our quality. We use only the purest niobium as our input material. This ensures that you benefit from a very high level of material purity.

- Pure niobium melted quality.
We supply our niobium ready for melting in sheet, ribbon or rod form. We are also very happy to manufacture complex parts.
Our pure niobium has the following properties:
- High melting point of 2 468 °C
- High ductility at room temperature
- Recrystallization at between 850 °C and 1 300 °C (depending on the level of
deformation and purity)
- High resistance against aqueous solutions and metal melts
- High solubility for carbon, oxygen, nitrogen and hydrogen (risk of embrittlement)
- Superconductivity
- High level of biocompatibility
