Niobium is one kind of color steel gray lustrous rare refractory metal, the melting point of 2467 ℃, the density is 8.6g/cm3. Niobium has good low temperature plasticity, can be cold pressure processing into a variety of forms, plate, wire rod products. High strength Nb, ability, more than 1000 ℃ still has enough strength, plasticity and thermal conductivity. Superconductivity is best at very low temperatures, such as in the minus 260 degrees Celsius and the resistance is close to zero, is currently the most important superconducting materials.
