Niobium and tantalum are the "twin brother."

Rare metal tantalum and niobium belong to the same group elements in the periodic table, because of their very similar physical and chemical properties, and they grow together in the same ore body, therefore tantalum and niobium is known as the "twin brother" in the metal. Tantalum Tungsten Alloy.

In 1801 and 1802, British chemist Charles Hatchett and Swedish chemist Ike Berg has discovered Tantalum and niobium successively. Ta and Nb is mainly in the tantalum-niobium iron ore and a small amount in tungsten ore and some rare earth ore. Tantalum and niobium have compressive and wear-resistant properties, so they are also excellent superconducting materials. Niobium and tantalum are the "twin brother."
