Tantalum Overview The texture of the tantalum is very hard and the hardness can reach 6-6.5. Its melting point is as high as 2996 °C, only after carbon, tungsten, rhenium, and osmium. Tantalum is malleable and can be drawn into a thin foil. Its coefficient of thermal expansion is very small, and it only expands by 6.6 parts...Continue Reading

Tantalum belongs to the refractory metal group and is widely used as a minor component in alloys. Its chemical properties are excellent, no matter whether it is cold or hot, it does not react with hydrochloric acid, concentrated nitric acid and “Aqua regia”. Its chemical inertness and relatively low price make it a good alternative...Continue Reading
