For Jewelry High Purity 99.95% Bright Niobium Plate Sheet Superconducting
Introduction
Niobium is a soft, ductile transition metal with excellent corrosion resistance. Its oxide, niobium pentoxide, protects the metal’s interior from corrosion, similar to aluminium oxide and zinc oxide.
Key features of niobium:
Enhances stainless steel’s high-temperature strength and reduces tempering brittleness.
Improves steel’s strength, toughness, and high-temperature creep resistance.
Small thermal neutron absorption cross-section, making it suitable for nuclear reactors and fuel packaging.
High superconducting transition temperature — ideal for superconducting materials and magnets.
Niobium plates and foils are widely used in chemical, aerospace, medical, electronics, and superconducting applications.
