ASTM B392 Niobium Alloy Bars
Niobium is a color steel gray shiny rare refractory metal, melting point of 2467 ℃, density of 8.6g/cm3. niobium has good low-temperature plasticity, can be cold pressed and processed into a variety of shapes of plates, wires and rods products. Niobium has high strength and ability, above 1000℃ still have enough strength, plasticity and thermal conductivity. Superconductivity at very low temperatures is the best, such as at minus 260 degrees Celsius when the resistance is close to zero, is currently the most important superconducting materials.
We can provide: Zirconium Alloys, Titanium Alloys, Niobium Alloy and other products.
