Niobium and tantalum

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties Their properties of hardness conductivity and resistance to corrosion largely determine their primary uses today The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines
