In order to solve the problem that the different sections of the existing composite orthopedic wire have different characteristics, the invention provides a composite orthopedic wire with large elongation. The composite orthopedic wire comprises a tubular outer layer and a strip-shaped core material, wherein the strip core material is arranged in the tubular outer layer, and the strip-shaped core material and the tubular outer layer are pressed at the junction of the two to form a bonding interface. By adopting the technical proposal of the invention, the orthopedic wire has the same characteristics in the length direction, and the composite characteristics of the real composite material are truly excellent. The composite orthopedic wire of the present invention is used in the field of orthodontic treatment.
