The invention discloses a method for producing Cu-Ti alloy with high strength and high elasticity, comprising Ti:3.0-4.0wt%, the third element groups: 0.01-0.5wt%. Said method comprises following steps: adding main and auxiliary material to non- vacuum medium-frequency induction furnace, fusion casting with the protection of inert gas; rolling the got casting billet, controlling finishing rolling temperature of hot rolling and intermediate annealing temperature of cold rolling to be higher than alloy solvus, solution treatment or recrystallization anneal treatment at 750 -850 Deg. C, aging treating at 350 -450 Deg. C for 5-20 hours. This invention is characterized in that the phase structure and grain size of alloy are controlled through proper production process, and the comprehensive properties of alloy are greatly improved.
