In metallurgical industry, niobium is mainly used to make high temperature resistant alloy steel and improve the strength of steel. In the smelting of carbon steel, only a few parts per million of niobium can be added to increase the strength of steel by one-third L. Super alloy made of niobium and tantalum with a series of metals such as tungsten, aluminum, nickel, cobalt and vanadium. In the mechanical industry, made of niobium, tantalum carbide carbide carbide tool, can withstand the high temperature of 3000 ℃, the hardness can be the hardest substance in the world --, diamond. Tantalum is an ideal biocompatible material in medicine. When it is in direct contact with human bone, muscle tissue and liquid, it can adapt to biological cells, with excellent affinity, almost no stimulation and side effects on the human body. Tantalum can not only be used to make bone plates, screws and clamps for the treatment of fractures, but also can be directly used to repair bones with tantalum plates and plates and replace broken bones caused by trauma with tantalum strips. Tantalum wire and tantalum foil can be used to suture nerves, muscle keys and blood vessels above 1.5 mm. Extremely fine tantalum wire can replace tendons or even nerve fibers. Tantalum gauze and mesh woven from tantalum silk can be used to repair muscle tissue.
