Special Metals manufactures excellent quality NIOBIUM ROUND BAR with assorted types. We offer highly strong bars for several industrial applications. We produce these bars with excellent performing Niobium material grade for various acerbic applications. It exhibits excellent features obtained from material with excellent durability and efficient workability. These bars are available in various sizes and dimensions, suitable for many applications. Its diameter and thickness depend on use. Whereas shapes like square, rod, cylindrical, flat, rectangle etc. Are obtained with admirable formability.

Why is NIOBIUM preferred?

Niobium is a popular material with existing strength and excellent conflict to corrosion in addition to oxidation. It forms a niobium oxide layer when it is exposed to the atmosphere containing air and moisture. The layer is a defensive barrier to block the additional air and moisture interference. As a result, it averts further corrosion incidence.

Main Features of NIOBIUM:

  • Supreme Malleability
  • Higher Melting Point
  • Low Density
  • Heat resistant

NIOBIUM ALLOY ROUND BAR is a bar produced to work in extreme conditions. It is exceedingly prolonged with higher thermal conditions. These bars are formed with the capability of working in higher pressures. It is not rusted in general conditions as well as it is protected from oxidation. These bars defy heat corrosion at a wide temperature range. It includes very high temperatures due to a higher melting point that supports efficient working at higher temperatures. Our bars show admirable wear strength to extreme heat and sustain higher pressure without affecting the strength of the bars.

PURE NIOBIUM ROUND BAR is applied in electrical equipment due to its excellent electrical conductivity. The aviation sector benefits from working with these solid and rigid bars with a low density of bars. Also, it is an excellent option for acidic surroundings and chemical processes as these bars provide advanced decomposition resistance. We offer our bars to use in high-pressure systems with excellent tensile strength, toughness, and hardness.

NIOBIUM ROUND BAR Applications:

  • It is used in Jewellery making.
  • It is used in chemical and acidic processing plants.
  • It is used in the Electrical and Electronics Industry for Sodium Vapor Lamps, Capacitors.
  • It is used in Aviation Industries for airplane engines.
