Niobium is a shiny, white, soft, and ductile metal, and takes on a bluish tinge when exposed to air at room temperatures for a long time. It is a component of some stainless steels and also alloys with nonferrous metals. These alloys have good strength and other properties, and are used in pipeline construction. The metal has a low capture crosssection for thermal neutrons and so finds use in the nuclear industries. The metal is used in arc-welding rods for some grades of stainless steel. It is used in advanced engineering systems;Some magnets contain niobium and superconductive magnets are made with Nb-Zr alloy wire.
