Description

 

Niobium is a soft, grey, crystalline, ductile transition metal which has a very high melting point and it is corrosion resistant. Its melting point is 2468℃ and boiling point 4742℃. It is has the largest magnetic penetration than any other elements and it also has superconductive properties, and a low capture cross section for thermal neutrons. These unique physical properties make it useful in super alloys used in the steel, aerospace, shipbuilding, nuclear, electronics, and medical industries.

 

We produce R04200, R04210 seamless tubes/pipes, welding tubes/pipes, capillary tubes which meet ASTM B 394-98 standard and the sizes can be customized as per your required dimensions. We will do our best to fulfill customers' needs and markets' demands by providing a great variety of customized products. Taking advantages of our high quality niobium oxide raw material, advanced equipment, innovative technology, professional team, we tailored your required products. You may tell us all your requirements and we dedicated in manufacturing upon your needs.
