A high-strength and high-damping AlZn bimetal alloy and a preparation method thereof are provided in the present application, belonging to the field of bimetal alloy materials. The high-strength and high-damping AlZn bimetal is obtained from an Al alloy and a Zn alloy or Zn; the bimetal is structured by an Al alloy skeleton and its embedded Zn alloy; the alloy material has the high strength of an Al alloy and the high damping performance of a Zn alloy.

Disclosed is a method for manufacturing a zinc wire. The method comprises melting a zinc ingot at a first temperature of 420 C. to 650 C. to form a molten zinc. Further, the method comprises calibrating a set of impurities in the molten zinc. Furthermore, the method comprises maintaining the molten zinc at a second temperature between 400 C. to 600 C. Subsequently, the method comprises fluxing the molten zinc to remove a non-metallic impurity. Further, the method comprises transferring the molten zinc into a casting mould to form a cast bar. Furthermore, the method comprises continuously feeding the cast bar from the casting mould to a rolling mill to form a rolled zinc wire rod. Finally, the method comprises drawing a zinc wire rod from the rolled zinc wire rod.
