A copper alloy material with high strength, high thermal resistance, high corrosion resistance, and excellent bending processability, and a method of producing the same are disclosed. The copper alloy material includes 5.0 to 40.0 wt% of Zn, 0.5 to 5.0 wt% of Fe, 0.5 to 2.0 wt% of Sn, 0.01 to 0.3 wt% of Ni, the remainder of Cu, and trace amounts of unavoidable impurities, based on 100 wt%, and exhibits characteristics such as high tensile strength, elongation percentage, and electrical conductivity, excellent bending processability, and the like. The copper alloy material may further include one element or more selected from the group consisting of Si, P, Al, Mg, and Ca in an amount of 1 wt% or less. The method of producing the copper alloy material includes obtaining molten metal, obtaining ingot from the molten metal, hot rolling by heating the ingot to 800 to 900℃, first cold rolling, heat treating at 400 to 500℃ for 5 to 10 hours to remove stress, subsequent cold rolling, and annealing at 600 to 800℃ for 10 to 60 seconds. |
