PROBLEM TO BE SOLVED: To provide a zirconium alloy whose growth by irradiation is suppressed, and which has high corrosion resistance and is utilizable for a channel box or the like. SOLUTION: The zirconium alloy has a composition comprising, by weight, 1.20 to 1.70% tin, 0.18 to 0.24% iron, 0.07 to 0.13% chromium and 0.28 to 0.37% iron+chromium, also comprising at least one kind of element selected from niobium, tantalum and vanadium by≤0.6% in total, and the balance zirconium with inevitable impurity elements. Alternatively, the other zirconium alloy has a composition comprising 1.20 to 1.70% tin, 0.24 to 0.55% iron, 0.07 to 0.13% chromium, 0.31 to 0.68% iron+chromium, and the balance zirconium with inevitable impurity elements.
