The industrial value of niobium is mainly reflected in multiple fields such as aerospace, steel industry, superconducting materials, etc.

Firstly, in the aerospace industry, niobium alloys are used to manufacture high-temperature components such as aircraft engines and spacecraft components. Due to its excellent high-temperature resistance, niobium can maintain stable performance under extreme conditions, which is crucial for the aerospace industry.

Secondly, niobium is widely used in the steel industry. By adding niobium to steel, the strength and toughness of the steel can be significantly improved, making the manufactured steel structure more durable and able to withstand greater loads and pressures. About 85% to 90% of niobium in the world is used in the form of niobium iron for steel production.

In addition, niobium also has excellent performance in the field of superconducting materials. Niobium titanium alloy is a common superconducting material that can achieve zero resistance at low temperatures and is widely used in high-tech fields such as magnetic resonance imaging (MRI) equipment and particle accelerators.

In summary, the industrial value of niobium is not only reflected in its wide range of applications, but also in its ability to significantly improve the performance and quality of related products.
