Introduction to the composition and parameters of niobium tubes
Niobium tubes Niobium capillaries Pure niobium tubes Niobium alloy tubes
Grade:
Pure niobium RO4200, purity 99.95%
Pure niobium RO4210, purity 99.99%
Appearance: The inner and outer surfaces of the tube present a uniform metallic luster, without oxidation, hydrogenation discoloration, scratches, deformation, burrs, etc.
Features: The density of niobium (Niobium) is 8.57g/cm³, the melting point is 2477°C, and the boiling point is 4744°C.
Niobium is a silver-gray, soft and ductile rare high-melting-point metal, and is currently the most important superconducting material.
