Application：Niobium and niobium alloy rod, wire has high melting point, corrosion resistance, good cold
working propertiesand other characteristics, widely used in chemical, electronics, aviation and aerospace
and other fields. Niobium and niobium alloy bars are used as structural materials of aircraft engines and
rocket nozzles,reactor internal components and sheath materials,production resistant to nitric acid,
hydrochloric acid or sulfuric acid corrosion conditions under a variety of corrosion-resistant components.
Adding zirconium niobium materials can significantly improve oxidation resistance and strength, niobium and
niobium-zirconium alloy wire is extensively used to manufacture high-pressure sodium lamps and electrolytic
capacitor anode lead.Appearance Quality: cold and annealed bar surface should be free of cracks, no folds,
No porosity, metallic and non-metallic inclusions,heavy leather, residual lubricants, oxides and other dirt.
Thermal processing state bar surface should be free of cracks, folds, re-skin and other effects subsequent
processing defects.
