EB Furnace Smelted , Niobium Ingots , 99.95%(3N5) Purity , AS Cast Ingots 

Niobium is a soft, grey, crystalline, ductile transition metal which is used in various superconducting materials. Its melting point is 2468℃ and boiling point 4742℃. It has the characteristics of high temperature resistance, high corrosion resistance and good ductility. Therefore, niobium and its alloy are widely used in electronics, iron and steel industry, chemical, jewelry, superconducting, engineering, aviation, aerospace industry etc.

We produce R04200, R04210 ingots which meet ASTM B 391-96 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. Our standard Ingot size is nominally φ290mm, φ210mm, φ150mm. And we also produce Niobium as rod, wire, plate, sheet, tube, disc, sputtering targets, machined parts and other shapes are available by request.Our QC control our products quality through the raw material source till the whole production line and finally deliver to our customers in order to make sure you purchase our products with stable and same quality for each lot. They use Metallographic microscope, Hand-held X ray Fluorescence, Electronic tensile testing machine etc., instruments to inspect the material and products and issue the COA for each lot. We have been certified by ISO9001:2015.

Application: To produce Niobium plate/foil/tube/wire and other process various niobium mill products which are widely applied for pharmacy, semiconductor, aviation and aerospace, nuclear, high temperature assemblies and other fields.
