Description of Niobium Sheet and Plate

Niobium (Nb), a transition metal with atomic number 41, is known for its high melting point (2,468°C), excellent corrosion resistance, and superconducting properties at cryogenic temperatures. It has a density of 8.57 g/cm³ and is highly stable under extreme conditions, including exposure to acids and alkalis. Niobium is ductile and can be easily formed into sheets and plates, making it suitable for high-performance applications in aerospace, medical, and nuclear industries. Its ability to maintain strength at elevated temperatures and its biocompatibility further enhance its utility in advanced technologies.

How to select Niobium Sheet and Plate

Niobium sheets and plates have good strength, durability, and resistance to extreme conditions. They are widely used in aerospace, superconducting technology, chemical processing, and medical devices. Below are the main factors to select a suitable Niobium sheets and plates

Thickness and Size

  • Thicker plates for structural use, thinner sheets for precision or superconducting applications.

Purity:

  • High-purity (99.9% or higher) is required for superconducting or medical applications.

Alloy Composition:

  • Nb-Ti or Nb-Zr alloys for enhanced strength or corrosion resistance.

Surface Finish:

  • Smooth, polished finish for medical or high-tech applications.

Mechanical Properties:

  • Tensile strength, elongation, and hardness depend on the intended use.
