Niobium and niobium alloy have high melting point and good corrosion resistance and cold-workability, they entensively applied to chemical,electronic,aerospace industry.And are used as structure materials of aeration jet engine for manufacturing rocket,inner component of reactor and corrosion-resistace component in HNO3,HCL,H2SO4 enviroment. Adding Zr into Nb can makely improve strength and oxidation resistance of alloy matericals, so Niobium and Nb-Zr alloy wire are massively used as anode lead of electrolyte capacitor and for manufacturing high-voltage sodium lamp.
