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.

 

Niobium plate, sheet, strip and foil are manufactured by ASTM B391 niobium ingots.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.
