The texture of tantalum is very hard, tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible hardness can reach 6-6.5. Its melting point is 2996℃, third only to tungsten and rhenium. Tantalum is malleable and can be drawn into filaments or made into thin foil. Its coefficient of thermal expansion is very small, expanding only 6.6 millionths for every degree Celsius increase. In addition, it is very tough, even better than copper.

Tantalum also has excellent chemical properties and is highly resistant to corrosion. No reaction was found to hydrochloric acid, concentrated nitric acid and aqua regia under hot and cold conditions. Soaking tantalum in sulfuric acid at 200℃ for one year only damaged the surface layer by 0.006 mm. Tungsten molybdenum tungsten plate, plate, bar, molybdenum rods, tungsten, molybdenum, tungsten crucible, molybdenum crucible experiments show that tantalum under the often, the alkali solution, chlorine, bromine water, dilute sulphuric acid and many other drugs don work, only under the effect of hydrofluoric acid and hot concentrated sulfuric acid to respond. Such a situation is relatively rare in metals.

Tantalum has a wide range of applications due to its properties. In the production of various inorganic acids in the equipment, tantalum can be used to replace stainless steel, the service life is dozens of times higher than stainless steel. In addition, in chemical, electronic, electrical and other industries, tantalum can replace the tasks that used to be performed by the precious metal platinum, so that the cost is greatly reduced.

In addition, tantalum is an important element in the production of super-strong, corrosion-resistant and heat-resistant steel alloys, which can provide special materials necessary for developing space technologies such as rockets, spaceships and jets. Non-magnetic alloys made of tantalum and tungsten are widely used in the electrical industry, especially tantalum carbide, which is composed of tantalum and carbon. Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible with it made of turning tool, can be high speed cutting many hard alloy; It can be used to replace the hardest alloys or stones. Therefore, tantalum is also considered as a "vitamin" in smelting.

Tantalum can also play an important role in modern medicine. Research has shown that tantalum is not only harmless to the human body, but also that human muscles can grow in it, which is called biocompatibility in medicine. Doctors use tantalum properties to repair and seal up cracks and defects in fractured skulls and limbs. Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible, also, tantalum can be made into a tenth thinner than a human hair, used as sutures for internal surgery, or embedded in artificial eyeballs. It can even replace tendons and nerve fibers. Doctors make an artificial ear from a tantalum plate, attach it to the head, and graft skin from the leg. Over time, the graft grows so well that it is barely recognizable as an artificial tantalum ear
