Niobium Bars are primarily made up of Niobium (Nb 99.9%), with small amounts of Tantalum, Titanium, and Tungsten added to boost their performance. They have a density of 8.57 g/cm³, a melting point of about 2477°C, and a tensile strength ranging from 275 to 550 MPa. This material is known for its outstanding ductility, resistance to oxidation, and thermal conductivity, maintaining its mechanical properties even at high temperatures. Niobium’s superconducting characteristics and its ability to create stable oxides make it an excellent choice for electrical and high-temperature applications where strength and corrosion resistance are essential.
