Niobium plate and niobium plate applications
Niobium sheetsTimber and plates are used in industrial, electric light sources, heating and thermal insulation 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 largest demand is for iron and steel enterprises, and the materials are mainly used for cold-rolled pickling tanks, jet pumps and their system pipe fittings.
