Niobium Wire Application

The niobium wire is mainly used in the field of electric light source, which is used to make the luminescent village material of high pressure sodium lamp. It has the advantages of high luminous efficiency, low power consumption, long service life and strong ability to penetrate fog. Niobium wire is also used in chemical industry, superconducting materials, high temperature metallurgy and other fields.
