Special requirements to be agreed on by the supplier and buyer of negotiations |
cold and annealed rods are free of cracks, folds, holes, metal and non-metallic inclusions, cold-lap, residual lubricant, oxides and other smudges on the surface while hot treatment rods are free of cracks, folds and double-skin.
[ Niobium tube]Application:
Niobium Tube and Niobium Pipe are used in steel, ceramics, electronics, nuclear energy, and superconductors.
Niobium Capillary Tube and Niobium Zirconium Capillary Tube are often used in high-pressure sodium lamp produc
Niobium pipe is mainly used as spinning of thin tube blank, thermocouple cannula and other special purposes.
[ Niobium tube ]Advantage:
Excellent Corrosion Resistance
Good resistance to effect of heat
