The invention discloses a preparation method of a high-performance cube texture nickel base alloy baseband, and belongs to the technical field of preparation of industrialization texture metal basebands for high-temperature coating conductors. The method is characterized by comprising the following steps: the preparation of an initial nickel-tungsten-phosphorous alloy billet; performing cold rolling on the initial nickel-tungsten-phosphorous alloy billet; performing primary recrystallization annealing on the cold-rolled nickel-tungsten-phosphorous alloy baseband; and performing high-temperature recrystallization annealing on the nickel-tungsten-phosphorous alloy baseband. According to the invention, the preparation technology is simple, the prepared nickel base alloy baseband is free from the ferromagnetic property in the liquid nitrogen temperature zone, the mechanical strength is higher, and the method is suitable for industrial production.
