Tantalum is a chemical element; it has symbol Ta and atomic number 73. Previously known as tantalium , [ citation needed ] it is named after Tantalus , a figure in Greek mythology. [ 11 ] Tantalum is a very hard, ductile , lustrous , blue-gray transition metal that is highly corrosion-resistant.
Natural tantalum (73 Ta) consists of two stable isotopes: 181 Ta (99.988%) and 180m Ta (0.012%). There are also 35 known artificial radioisotopes, the longest-lived of which are 179 Ta with a half-life of 1.82 years, 182 Ta with a half-life of 114.43 days, 183 Ta with a half-life of 5.1 days, and 177 Ta with a half-life of 56.56 hours.

The tonne (/ t ʌ n / ⓘ or / t ɒ n /; symbol: t) is a unit of mass equal to 1,000 kilograms.It is a non-SI unit accepted for use with SI.It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton (United States customary units) and the long ton (British imperial units).
(Ta – 2.5% W) → also called 'tantaloy 63 metal.' The percentage of tungsten is about 2 to 3% and includes 0.5% of niobium. This alloy has a good resistance to corrosion and performs well at high temperatures. An example application is piping in chemical industries. [1] (Ta - 7.5% W) →
