Niobium sheet and niobium plate applications
Niobium sheetsand plates are used in industrial, electric light sources, heating and insulation, and electric vacuum equipment. High purityNiobium sheetsIt has higher requirements for purity and uniformity, and can be used as a cavity material for superconducting linear colliders.Niobium platesThe most demanded materials are in steel companies, where materials are mainly used in cold-rolled pickling and soaking tanks, jet pumps and their system fittings.
