3.features
Niobium features high melting point , low vapor pressure , good cold processability ,excellent chemical stability , good resistance to corrosion , high dielectric constant ,in surface oxide film .widely used in many industries such as electronics ,metallurgy, chemical processing , hard alloy cutters , aerospace and aviation
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.
4.Guaranteed purity.and product shows:
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.
