Disclosed are a hybrid copper alloy with high strength, high elastic modulus, high corrosion-resistance, wear resistance, and high conductivity and a method for producing the same. The hybrid copper alloy has a bi- or multi-layer structure in which (A) a copper alloy Cu (A) selected from the group consisting of Cu—Zn, Cu—Al, Cu—Ni—Zn, Cu—Ni—Si, Cu—Ni—Sn and Cu—Ni—Si—Sn is bonded to a copper alloy Cu (B) selected from the group consisting of Cu—Cr, Cu—Zr, Cu—Ag, Cu—Mg and Cu—Cr—Zr or molten alloys of a copper alloy Cu (A) and a copper alloy Cu (B) are cast in parallel such that a joint interface between these alloys is present. The hybrid copper alloy exhibits high strength, high elasticity, high corrosion resistance, abrasion resistance and high conductivity that cannot be obtained by a single copper alloy known to date.
