Product Description
Baoji Zhipu Non-Ferrous Metals Processing Co.,Ltd is one of the most famous China niobium tube manufacturers and suppliers, welcome to wholesale cheap niobium pipe products from our company and factory. 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.  Product name niobium tube standard GB/T8183-1987 grade RO4200-1,RO4210-2 diameter φ2.0-100mm thickness 0.2-5.0mm length 200mm-8000mm specification Φ0.2~Φ8mm,T0.015~0.5mm highest accuracy od Φ±0.003mm,T±0.005mm,L±0.05mm surface under a microscope,the inside and outside of tube surface present metallic luster ,no oxidation,hydrogenation,discoloration,scratches,deformation,burr Medical composition: grade Element content(%) Nb Fe Si Ni W Mo Ti Ta O C H N Nb1 remain 0.004 0.004 0.002 0.005 0.005 0.002 0.05 0.012 0.0035 0.0012 0.003 Nb2 remain 0.01 0.01 0.005 0.02 0.01 0.004 0.07 0.015 0.0050 0.0015 0.005 Physical property: standard Tensile Strength,pounds / inch (MPa)) yield strength(The residual deformation of 0.2%)pounds / inch (MPa)) Elongation %inch (25.4 mm) gauge RO4200-1RO4210-2 18000(125) 12000(85) 25 Application: 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.
