Along with tantalum, niobium is one of the top five heat and wear resistors. Niobium is used with iron and other elements in alloys together with a variety of nonferrous metals, such as zirconium. Niobium alloys are mechanically strong and are often used in pipeline construction. The metal is used in super alloys for heat engines and heat resistant equipment
