Firmetal - Niobium Sheet & Plate
Niobium metal melting point is 2468˚C, the density of 8.6 g/cm3. Niobium also has the characteristics of corrosion resistance, high temperature resistance and malleability. Its products are widely used in electronics industry, steel industry, chemical industry, optics, gemstone manufacturing, superconducting technology, aerospace technology and other fields. Niobium sheet and plate is the most common form of Nb product.

Niobium Sheet & Niobium Plate Standard
All niobium and niobium alloys sheet & plate products follow standard ASTM B393, such as pure niobium sheet & plate (R04200, R04210), Nb1Zr (R04251 R04261), Nb10Zr , C-103, Cb-752, C-129Y, FS-85 , Nb-50Ti sheet & plate and so on.
Niobium Sheet & Niobium Plate Production Technology
- Niobium sheet & plate is usually made by cold rolling, the total processing rate is controlled at 80% ~ 90% of slab thickness, and the total processing rate is 6% ~ 8% of slab thickness. In order to ensure the surface quality of sheet metal, the blank of forging forming must be not defective, polluted, and the roller surface must be clean.
- Niobium alloy sheet, niobium strip and niobium foilprocessing technology and heat treatment specification is as follows: electron beam melting of Nb ingot — at room temperature (or < 400 degree Celsius) forging — annealing — roughing — annealing — strip rolling — annealing — foil rolling — heat treatment.
- Pure niobium sheet, niobium strip and niobium foil, niobium-1%zirconium sheet strip and foil, along with other niobium alloys sheet, strip and foil are all made by above technology.
