The invention discloses a constant-elasticity alloy with the high Q value and low frequency temperature coefficient and a preparation method of the alloy, and relates to the technical field of elasticalloys. Components of the alloy comprise, by weight percent, not larger than 0.030 of C, not larger than 0.50 of Si, not larger than 0.50 of Mn, 44.00-45.00 of Ni, 1.50-4.00 of Cr, 4.90-8.00 of Cr+Mo, 2.50-3.5o of Ti, 0.40-1.20 of Al, 0.10-0.30 of Cu and the balance Fe and inevitable impurities. The preparation method of the alloy comprises the steps that after preparation, an alloy cast ingot issubjected to vacuum smelting, and after homogenizing annealing, the alloy cast ingot is forged into an alloy square blank; then the alloy square blank is subjected to hot rolling to form an alloy rod; and the rod is subjected to aging treatment for 2-4 h under the temperature ranging from 650 DEG C to 750 DEG C, furnace cooling is carried out to room temperature to obtain a finished product, andQ of the finished product i
