The invention discloses high-temperature corrosion-resisting copper alloy and a preparation method thereof. The high-temperature corrosion-resisting copper alloy comprises the following raw materialsin parts by weight: copper, aluminum, iron, nickel, manganese and an additive; and the preparation process of the high-temperature corrosion-resisting copper alloy comprises the following steps: material crushing, high-temperature smelting, cooling casting and solution treatment. In the high-temperature corrosion-resisting copper alloy disclosed by the invention, the manganese, the iron and the nickel all are high-purity metals; the aluminum is aluminum oxide; the quality of the high-temperature corrosion-resisting copper alloy can be effectively improved; the performances of the high-temperature corrosion-resisting copper alloy are improved; the high-temperature corrosion-resisting copper alloy is good in mechanical properties, good in corrosion resistance and fatigue strength and is relatively high in heat resis
