To provide a zirconium alloy material having high corrosion resistance regardless of thermal history during its manufacturing process.
The zirconium alloy material is obtained by providing a zirconium alloy containing on the mass basis: 0.001% to 1.9% of Sn, 0.01% to 0.3% of Fe, 0.01% to 0.3% of Cr, 0.001% to 0.3% of Ni, 0.001% to 3.0% of Nb, 0.027% or less of C, 0.025% or less of N, 4.5% or less of Hf and 0.16% or less of O with the remainder being inevitable impurities and zirconium. Then, a cold work is applied to at least a surface thereof so as to have a plastic strain of 3 or more or a Vickers hardness of 260 HV or more and the surface is planarized by a mechanical or chemical polishing method, while the layer to which the cold work is applied is remained.
