Introduction
Niobium rods are manufactured from niobium powder through forging and polishing processes. Niobium is a refractory metal with a melting point of 1772°C, making it ideal for high-temperature applications. Refractory metals, including niobium, are characterised by:
High melting points
Low vapour pressure
High elastic modulus
High thermal stability
Low coefficient of thermal expansion
Compared to other refractory metals, niobium has a relatively low density of 8.6 g/cm³, making it strong yet lightweight.
Niobium rods are widely used in steel, metallurgy, atomic energy, superconductors, medical equipment, and aerospace applications.

Applications
Niobium and niobium alloy rods are widely used due to their high melting point, corrosion resistance, and excellent cold-working performance. Typical applications include:
Aerospace & Aviation: Structural materials for aircraft engines and rocket nozzles
Nuclear Industry: Reactor internal components, cladding materials
Chemical Industry: Corrosion-resistant components exposed to nitric, hydrochloric, or sulfuric acids
Electronics: Specialised components requiring high-temperature stability and conductivity
