Tantalum material has high temperature resistance, good strength and stiffness, and is a high-quality material for making heating components, insulation components, and loading vessels for vacuum high-temperature furnaces. The main use of tantalum material is still to make capacitors. Tantalum capacitors are currently the most high-performance capacitors. Tantalum wire is used as the anode lead of tantalum capacitors because tantalum has excellent physical and chemical properties, such as high melting point, low coefficient of thermal expansion, excellent toughness and ductility. Especially, it has extremely excellent corrosion resistance and does not react with hydrochloric acid, concentrated nitric acid, and aqua regia. Tantalum wire has also gained important applications in the medical field due to its biocompatibility, allowing human muscles to grow on it. Therefore, it can be used to compensate for muscle tissue and suture nerves and tendons.

Tantalum niobium is a high-quality material that is resistant to acid, alkali, and liquid metal corrosion. It can be used in the chemical industry to make steamers, heaters, coolers, and various vessel components.

Metal niobium has high temperature resistance and strength, and still has sufficient strength, good plasticity, and thermal conductivity above 1000 ℃. Superconductivity is best at extremely low temperatures, such as near zero resistance at around minus 260 ℃, making it currently the most important superconducting material.

Niobium wire and niobium zirconium alloy wire are widely used in fields such as chemistry, electronics, aviation, and aerospace due to their high melting point, corrosion resistance, and good cold working performance. Adding zirconium to niobium can significantly improve the material's oxidation resistance and strength. Niobium and niobium zirconium alloy wires are widely used in the manufacture of high-pressure sodium lamps and anode leads for electrolytic capacitors.
