The present invention relates to a zirconium based alloy composite having an excellent creep resistance and, more particularly, to a zirconium based alloy composite finally heat-treated to have the degree of recrystallization in the range of 40-70% in order to improve the creep resistance. The zirconium based alloy comprises 0.8-1.8 wt.% niobium (Nb); 0.38-0.50 wt.% tin (Sn); one or more elementsselected from 0.1-0.2 wt.% iron (Fe), 0.05-0.15 wt.% copper (Cu), and 0.12 wt.% chromium (Cr); 0.10-0.15 wt.% oxygen (O); 0.006-0.010 wt.% carbon (C); 0.006-0.010 wt.% s ilicon (Si); 0.0005-0.0020 wt.% sulfur (S); and the balance zirconium (Zr). The zirconium alloy manufactured with the composition in accordance with the present invention has an excellent creep resistance compared to a conventional Zircaloy-4, and may effectively be used as a nuclear cladding tube, supporting lattice and inner structures of reactor core in the nuclear power plant utilizing light or heavy water reactor.
