Product name: Niobium alloy rod niobium rod
Implementation standard: GB/T 14842-1993, ASTM B 392-95
Brand: Nb1, Nb2
Purity :99.99%
Product use:
Niobium and niobium alloy rod and wire are widely used in the fields of chemistry, electronics, aviation and aerospace because of their high melting point, corrosion resistance and good cold working performance. Niobium and niobium alloy bars are used as structural materials for aircraft engines and rocket nozzles, reactor internal components and cladding materials, and to make a variety of corrosion-resistant parts under conditions of nitric, hydrochloric or sulfuric acid corrosion. Adding zirconium to niobium can obviously improve the oxidation resistance and strength of the material. Niobium and niobium zirconium alloy wires are widely used in the manufacture of high pressure sodium lamp and anode leads of electrolytic capacitors.
