| Material： | Niobium |
| Specification： | Φ0.2～Φ8mm，T0.015～0.5mm |
| Standard： | GB/T8183-1987 |
| Grade： | RO4200-1，RO4210-2 |
| Surface Treatment： | under a microscope,the inside and outside of tube surface present metallic luster ,no oxidation,hydrogenation,discoloration,scratches,deformation,burr |
| Applications： | niobium and niobium alloy tube with high melting point,good corrosion resistance,cold working performance characteristics.Wildly used in chemical industry,electronic,aviation and aerospace industry.Is mainly used in the production of high pressure sodium lamp, aviation and aerospace engine structure material, chemistry reaction vessel, heat exchanger tube, reactor internal components and coating materials.Add zirconium in niobium can obviously improve the oxidation resistance and strength, the niobium zirconium alloy is manufactured into capillary supply sodium lamp manufacturing. |
Niobium metal is gray.melting point2468℃,boiling point4742℃，density8.57g/cm³.Niobium metal is stable in the air at room temperature.In the oxygen niobium metal not be completely oxidation.Under the high temperature niobium metal can be combined with C,N,S directly.And niobium metal can be with Ti,Zr,W to alloy.Not with inorganic acid or alkali, not soluble in aqua regia, but soluble in hydrofluoric acid.
