  • High melting point
  • Corrosion
  • Good cold working performance

558 - ASTM B394 Niobium Tube

Standard

  • Niobium Plate/Sheet – ASTM B391
  • Niobium Foil & Strip – ASTM B708
  • Niobium Tube – ASTM B394
  • Niobium Pipe – ASTM B394
  • Niobium Bar & Billet – ASTM B392
  • Niobium Rod & Wire – ASTM B392

The product application

Rod, wire materials are widely used in chemistry, electronics, aviation and aerospace and other fields.
Niobium and niobium alloy rods are used as structural materials of aero engines and rocket nozzles, reactor internal components and envelopment materials, and various corrosion resistant parts and components under the corrosion resistance of nitric acid, hydrochloric acid or sulfuric acid.
The addition of 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 lamps and anode leads for electrolytic capacitors. (Executive standard: ASTMB392-95).
