description The invention relates to a conductive electrolytic copper alloy and especially relates to a copper alloy for an electrified railway contact network and a preparation method of the copper alloy. The copper alloy for the electrified railway contact network comprises the following components by weight percent: 8.0%-11% of aluminum, 2.5%-4.5% of iron, 1.0%-2.0% of nickel, 1.0%-2.0% of manganese, 0.15%-2% of 5# rare earth and 78%-88% of copper, wherein the impurity is not more than 0.5%. The preparation method comprises the following steps of: dropping the bottom of a medium-frequency induction furnace and preparing an oven; smelting alloy; chemically testing; and tapping. The conventional alloy wind resistance is increased; the manufacturing cost of the material is 10% lower than that of QSi1-3 and CuNi2Si; and the copper alloy is an ideal copper alloy material for manufacturing accessories of the electrified railway (high-speed electrified railway) contact network.
