Niobium Foil / Strip

Niobium Foil / Strip processing technology

Electron beam smelting niobium ingots → forging at room temperature (or ≤400 c) → annealing → roughing → annealing → strip rolling → annealing → foil rolling → heat treatment
Niobium Foil can be pressed into Niobium Cup and Niobium Crucible.
Niobium Cup and Niobium Crucible can be used in corrosion resistant chemical industry and synthetic diamond industry, also used for making high pressure sodium lamp.
