Niobium Rod/Bar (Nb Rod/Bar)

HTNB1102

New product

Niobium rod and niobium bar are forged from metal niobium, and high-purity niobium metal has high ductility. Niobium has a very low capture cross-section for thermal neutrons, so it is quite useful in the nuclear industry. HM provides customized Niobium Rods and Niobium Bars with the shortest lead time and the best price.

Niobium Rod Application

Niobium rods and niobium alloy rods are used as structural materials for aero-engines and rocket nozzles, reactor interiors, and cladding materials, and for the production of various corrosion-resistant parts under the corrosion conditions of nitric acid, hydrochloric acid, or sulfuric acid. Adding zirconium to the niobium rod can significantly improve the oxidation resistance and strength of the material.

Niobium Rod Packing

The Niobium Rod will be packed in a wooden case supported with soft materials to ensure that the products thus packed will not shift inside the cases.
