Uses

Uses & Benefits
  • Niobium alloys are used in jet engines and rockets and spacecraft, beams and girders for buildings and oil and gas pipelines.
  • It is used superconducting magnets in particles accelerators, NMR and MRI equipment.
  
  • It has corrosion resistance and hence it is used to plate other metals.
  • Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
