Good Ductile Niobium Ingot Easily Fabricated High Corrosion Resistance

Ingot of Smelted Niobium , Niobium Ingot 99.9%(3N) - 99.95%(3N5) Purity , ASTM B 391-96​
 
Description
 
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.
 
Ingots are generally the least costly metallic form and useful in general applications. 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.
 
We smelt the high purity Nb2O5 we sourcing from the Chinese biggest hydrometallurgy plant by means of aluminothermic reduction to produce niobium aluminum alloy. Then the niobium aluminum alloy will be smelted in high Vacuum EB furnace to produce niobium bars with Nb content 99% up, which will be smelted again in high Vacuum EB furnace to be purified and produce Niobium ingots with purity 99.9% up. The size can be tailored by the customers’ requirements. We 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. 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.

Our Strength

• More than 20 years’ experiences in tantalum /niobium and its alloy smelting and deep processing, we make sure that we can provide you with the best quality products with competitive price. We have entered a long-term contract with the Chinese biggest tantalum/niobium hydrometallurgy smelter to assure our stable and high quality raw material. The full and strict quality control system throughout the whole production line from the raw material till the products ready for delivery, we reject the unqualified products timely to make sure only qualified products can be received by our customers.
   
  In addition, we offer various kinds of services to our customers such as OEM, forging services, sintering services, laser cutting services, rolling services, milling services, trade in services etc. Please feel free to send us the enquiries as long as you require services.
   

  We have been verified by ISO 9001Quality Management System Authentication. We now owns core equipment such as domestic advanced EB furnace, high vacuum Annealing Furnace, plate and strip rolling mill, High precision surface grinding machine etc. Advanced equipment not only produces our fine quality products but also ensure us provides the processing services such as smelting, forging services, sintering services, laser cutting services, rolling services, milling services etc.
