Niobium Rod / Bar

niobium rod

Application of Niobium Rod / Bar

Niobium Rod / Bar is widely used in chemical, electronic, aerospace and other fields for its properties of high melting point, corrosion resistance and good cold working performance.
Adding Zirconium to Niobium can obviously improve the oxidation resistance and strength of the materials.

niobium bar

Niobium and Niobium alloy rod / bar are used as structural material for aero-engines and rocket nozzles, internal components of reactors and coating materials, and various corrosion resistant parts under the conditions of nitric acid, hydrochloric acid or sulfuric acid corrosion.
