<p>Disclosed is a zirconium alloy material for a nuclear power reactor core, falling within the technical field of special alloy materials, and comprising the following components in percentage by weight: 0.4-0.8 percent of Sn, 0.75-1.1 percent of Nb, 0.20-0.50 percent of Fe + Cr, 0.20-0.35 percent of Fe/(Fe + Nb), 0.01-0.1 percent of Cu or Bi or Ge, 0.002-0.02 percent of Si or S, 0.06-0.15 percent of O, less than 0.008 percent of C, less than 0.006 percent of N, and the balance being Zr. On the basis of a Zr-Sn-Nb system alloy, other components for improving the performance of the alloy are added, not only improving the corrosion resistance of the alloy, but also improving the mechanical properties and radiation resistance of the alloy, so that the requirements of high burnup of the nuclear power reactor on the structural materials of the core are met.</p> |
