Product manual

Tantalum, a metallic element, mainly exists in tantalite and co-exists with niobium. The texture of tantalum is very hard, the hardness can reach 6-6.5. Its melting point is as high as 2996ºC, second only to tungsten and rhenium, ranking third. Tantalum is malleable and can be drawn into a thin wire-like foil. Its coefficient of thermal expansion is very small. It only expands by 6.6% per degree Celsius. In addition, its toughness is very strong, even better than copper. Tantalum also has extremely high corrosion resistance. It does not react to hydrochloric* acid, concentrated nitric* acid and "aqua regia" regardless of whether it is under cold or hot conditions.
