PURPOSE:To obtain a Zr alloy having an excellent antinodular corrosive characteristic at low cost, by specifying the compsn. consisting of Nb, Sn, Fe, Cr, Ni and Zr. CONSTITUTION:The Zn alloy contains the compsn. consisting of, by weight, one or more kinds among 0.1-1.2% nb, 0.2-1.2% Sn, further <=0.25% Fe, <=0.20% Cr, <=0.3% Ni, the balance Zr with inevitable impurities, and has the excellent antinodular corrosive characteristic. the Sn content thereof is decreased as well as the specific ratios of Fe, Cr, Ni, etc., are added therein, by which the cost is lowered and the antinodular corrosive characteristic is improved.
