The demand for tantalum, niobium, titanium and their alloy materials in the aerospace and defense industries

France's demand for tantalum (Ta), niobium (Nb), and titanium (Ti) is primarily focused on the aerospace and defense sectors. Titanium alloys (such as Ti-6Al-4V) provide engine blades, fuselage fasteners, and rocket fuel tanks for aircraft; tantalum capacitors and niobium-based high-temperature alloys are used in the high-temperature components of jet engines and military radar communication systems.

In the fields of medical and bioengineering, titanium foil, titanium wires, and titanium alloy plates have become the preferred choice for artificial joints, dental implants, and MRI-compatible surgical instruments in France due to their biocompatibility. The chemical inertness of tantalum capillaries enables their use in cranial bone repair and vascular stent coatings. Some French enterprises are driving the continuous growth of the related implant market.

The demand for tantalum in the electronics and semiconductor industries is particularly prominent. French enterprises have purchased large quantities of tantalum capacitors to ensure the miniaturization and high stability of smartphones, automotive electronics, and 5G base stations. Niobium-titanium superconducting alloy rods and tubes are used in MRI magnets by the French medical industry, supporting the manufacturing of high-end medical equipment in France.

Energy, nuclear energy and the automotive industry jointly form the fourth major application sector. The niobium alloy cladding enhances the radiation resistance of nuclear fuel, while the titanium heat exchangers and marine wind power components that are resistant to seawater contribute to renewable energy. In electric vehicles and high-performance racing cars, titanium is used to lighten the batteries and exhaust systems, and niobium micro-alloyed steel makes the vehicle body stronger and lighter. Finally, the demands for chemicals, manufacturing and cutting-edge research continue to grow. French chemical giants use titanium corrosion-resistant pipes and reactors, and tantalum linings to resist strong acids; particle accelerators use niobium superconducting radiofrequency cavities to explore fundamental physics, and tantalum is even regarded as the key material for the next generation of superconducting quantum bits.
