ASTM B393

Niobium (symbol Nb, atomic number 41) is a refractory metal that plays a strategic role in many cutting-edge industrial sectors. Ductile, corrosion-resistant, and possessing remarkable superconducting properties, it is now indispensable in the fields of aerospace, nuclear energy, medicine, and energy. Concept Métal, a supplier specializing in non-ferrous and specialty metals, offers its expertise to assist you with the procurement of pure niobium and niobium alloys.

Physical and Chemical Properties of Niobium

Niobium has a density of 8.57 g/cm³ and an exceptionally high melting point of 2,477 °C, which classifies it as a refractory metal. In its pure form, it is a light gray, ductile, and relatively soft metal, which makes it easy to shape by rolling, forging, or cold working.

Its main strengths lie in:

Its exceptional corrosion resistance, particularly against hydrochloric, nitric, and sulfuric acids at room temperature.
Its biocompatibility, which makes it a material of choice for medical implants.
Its low-temperature at low temperatures: niobium-titanium (NbTi) and niobium-tin (Nb₃Sn) alloys form the basis of the most powerful superconducting magnets on the market.
Its high-temperature performance, which is utilized in superalloys for turbines and engines.

Industrial Applications of Niobium

Niobium is used in industries where technical demands are extreme:

Aerospace : added to nickel-based superalloys to improve their high-temperature creep resistance (turbine discs, blades, combustion chambers).
Nuclear : tubes and components for reactors, thanks to niobium's low neutron capture cross section.
Medical : surgical implants, stents, and biocompatible devices (prostheses, dental implants).
Superconductors : MRI scanners, particle accelerators, nuclear fusion projects (ITER).
Chemical Industry : heat exchangers, reactors, and piping exposed to corrosive environments.
Steel Industry : Ferro-niobium is used as an alloying element in HSLA (high-strength low-alloy) steels for structural applications, pipelines, and automobiles.
