What are the excellent properties of niobium screws?

The melting point of niobium is as high as 2996 ℃, and its boiling point is 4742 ℃. Screws made of niobium can maintain stability in high temperature environments and are not easily deformed. They can be used for connecting high-temperature components such as jet engine parts, gas turbines, rocket components, etc.
The surface of niobium can form a dense oxide film, which gives it excellent corrosion resistance and can withstand strong acids such as concentrated nitric acid, fuming sulfuric acid, as well as alkaline solutions of various concentrations. Therefore, niobium screws are suitable for corrosive environments such as chemical and marine environments.
Niobium has a high tensile modulus and hardness, resulting in screws with high strength. For example, hardened niobium screws have a higher ultimate strength, which can meet some high requirements for fastening strength.
Common ones include pure niobium screws, such as the R04210 pure niobium screw; There are also niobium alloy screws. We offer a variety of sizes, including different diameter specifications and customized lengths according to specific needs. We can also produce non-standard parts based on customer drawings and samples.
It is mainly used in the aerospace field such as aerospace engines and weapon thrusters, and can also be used in applications with high material performance requirements such as nuclear reactors, submarines, high-temperature furnace heating belts, and high-temperature molds.
