Niobium tube has excellent physical and chemical properties. In terms of physical properties, the density of niobium tube is about 8.57 g/cm3. The melting point of Nb pipe is as high as 2468 ℃, and Cb pipe has good strength and ductility. Niobium tubing can still maintain stable mechanical properties under high temperature environment. In addition, niobium tubings exhibit extremely low resistance and high critical magnetic field in the superconducting state, which is suitable for use in superconducting materials.
In terms of chemical properties, niobium tube has a strong affinity for oxygen and nitrogen, and it is easy to react with these elements at high temperatures. Niobium tubes have good corrosion resistance to a variety of acids, such as sulfuric and hydrochloric acid, but are more vulnerable to hydrofluoric acid. The Columbium tube forms a dense oxide film in the air, which enhances its corrosion resistance. The excellent chemical stability and biocompatibility of niobium tube make it widely used in many fields such as medical treatment, chemical industry and energy.

Niobium tube is mainly used to manufacture superconducting magnet and superconducting wire in the field of superconductivity. Because of its excellent superconducting properties and high critical magnetic field, niobium pipes are widely used in advanced technologies such as particle accelerators, nuclear magnetic resonance imaging (MRI) equipment and quantum computers. Niobium tubings are mainly used in the aerospace industry to make superalloy components and jet engine components. The excellent high temperature resistance and corrosion resistance of Cb tube make it suitable for extreme environments, ensuring the safety and reliability of aircraft. Niobium pipings are used in the chemical industry to make corrosion-resistant reactors, pipes, and storage tanks, particularly suitable for handling strong acids, bases, and organic solvents. Its excellent chemical resistance and strength ensure long-term reliability in harsh environments. Nb tubes are primarily used in the medical industry to make biocompatible implants and medical devices such as heart stents and artificial joints. Its excellent corrosion resistance and biocompatibility ensure safety and durability in the body. Columbium tubes are mainly used in the energy industry for deep-sea oil and gas extraction equipment, pipelines and storage tanks. In the nuclear energy industry, niobium tubes are used as a material for reactor components and cooling systems. Niobium tubes can be made into niobium rings. Niobium ring refers to its light, comfortable and anti-allergy, suitable for daily wear, especially for people who are allergic to metal.
