Niobium and niobium alloy have high strength at high temperature, and have relatively small density compared with other high temperature and high strength metals such as tungsten and tantalum. They are easy to process and shape, so they are often used as key components of rocket engines.
The superconducting transition temperature of niobium is high. The superconducting materials such as niobium titanium, niobium tin, niobium aluminum and germanium are not only used for power transmission, power generation, superconducting magnets and nuclear fusion control, but also for navigation devices in space vehicles, electromagnetic propulsion equipment for high-speed diving ships and superconducting high-speed trains.
Niobium corrosion resistance is good, can be used as heat exchanger, condenser, filter, agitator, etc. Niobium carbide can be used alone or in conjunction with tungsten carbide and molybdenum carbide for hot forging dies, cutting tools, jet engine turbine blades, valves, tail skirts and rocket nozzles.
The alloy steel containing niobium has high strength, good toughness and cold quenching resistance, which can be widely used in oil pipelines.
Main products and applications: Niobium: mainly used for superconducting barrier material; High temperature niobium alloy (niobium tungsten alloy, niobium hafnium alloy) : due to its good mechanical properties and stability of high temperature properties, it is mainly used in the field of aerospace (structural materials of rocket nozzle, etc.);
Niobium strip: backlight of LED; Niobium alloy tube: material of high pressure sodium lamp for electric light source.
