Niobium Tube

China’s niobium tube production adopts advanced forging and drawing processes. Through multiple forging and stretching, the niobium tube has uniform material, refined grains and excellent mechanical properties. The combination of intermediate annealing and final annealing treatments gives the niobium tube excellent ductility and mechanical properties, which can meet industrial applications in high-performance fields.

Among the leading niobium tube manufacturers in China, iTOP Metal has a strong R&D team dedicated to the development of high-performance niobium alloy and composite applications. We use advanced processes such as electron beam melting and annealing to ensure the high purity and uniformity of niobium tubes to meet the strict application standards of projects in application fields such as reactor vessels, superconducting key components and high-temperature structural parts. Among them, the quality and price of iTOP® niobium seamless tubes are unanimously favored by international project customers.

The melting point of niobium is as high as 2477°C, which enables niobium to maintain good mechanical properties and chemical stability in high temperature environments. Niobium can form a dense oxide film at high temperatures, which enhances its high temperature oxidation resistance and is suitable for use in extreme high temperature environments. At the same time, niobium is one of the few metals that can exhibit superconductivity at low temperatures (such as close to absolute zero).

Pure niobium tubes contain more than 99.9% niobium and have good corrosion resistance. They are used in chemical equipment (such as heat exchangers, reactors) and parts in the nuclear industry that require high temperature resistance and strong corrosion resistance. Niobium capillaries have extremely small inner diameters and thin walls, and are characterized by high precision and high strength. They are widely used in precision parts and high-precision pipelines or transmission elements in catheters and medical devices.

Due to the addition of titanium, niobium-titanium alloy tubes improve the strength and heat resistance of niobium, while maintaining good ductility and weldability, and have excellent oxidation resistance and corrosion resistance. Niobium-titanium alloy tubes are often used as high-temperature alloy materials for the manufacture of engine components and other structural parts in high-temperature applications. They are also used as corrosion-resistant pipes in chemical equipment and the nuclear industry.

Niobium-tantalum alloy tubes have stronger corrosion resistance in high temperature and acidic environments, maintain good toughness and plasticity, are suitable for the manufacture of complex shapes, and are often used in equipment in extremely corrosive environments in the chemical industry, such as acidic medium treatment systems and heat exchangers.

Niobium-tungsten alloy tubes have extremely high strength and wear resistance, can maintain good mechanical properties at extreme temperatures, and have excellent creep resistance. Widely used in the aerospace and defense industries, manufacturing rocket engine nozzles, aerospace engine parts, etc.

1. Chemical equipment: Due to the stability of niobium tubes in extreme chemical environments, niobium tubes are used to manufacture heat exchangers, reactors and piping systems, especially in high temperature and highly corrosive media.
2. Electronics industry: In vacuum electronic technology, niobium tubes are used to manufacture equipment such as electron tubes, vacuum switches and capacitors. The high melting point and low vapor pressure of niobium make it perform well in high vacuum environments, maintaining the efficient operation of equipment and extending its service life.
3.  Aerospace: Niobium tubes are used in rocket engine nozzles and combustion chamber components of aircraft engines due to their high temperature resistance, which need to maintain mechanical strength and corrosion resistance at extremely high temperatures.
4. Superconducting applications: Niobium tubes are an important material for manufacturing superconductors, especially superconducting materials such as niobium titanium alloys and niobium tin (Nb3Sn). In MRI equipment in the medical field, superconducting magnets made of niobium tubes are used to generate strong magnetic fields to help imaging.
5. Nuclear energy projects: In nuclear reactors, niobium tubes are used as structural materials in reactors due to their excellent high temperature resistance and corrosion resistance.
