Description:
Niobium and niobium alloy have high melting point and good corrosion resistance and cold-workability; they extensively 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-resistance component in HNO3, HCL, H2SO4 environment. Adding Zr into Nb can markedly improve strength and oxidation resistance of alloy materials.
