A low-boron-oxygen cutting line for one-way wire winding and a manufacturing method are provided. A core material comprises 55-65 wt % of copper, 0.001-0.03 wt % of boron, 0.05-1.0 wt % of other elements which are at least two of titanium, iron, silicon, nickel, manganese, aluminum, tin, phosphorus and rare earth, less than 0.5 wt % of inevitable impurity elements, and an allowance of zinc; and a surface comprises 35.0-45.0 wt % of copper, 0.001-3.0 wt % of oxygen, 0.0005-0.5 wt % of other elements, at least two of which are titanium, iron, silicon, nickel, manganese, aluminum, tin, phosphorus and rare earth, less than 0.5 wt % of inevitable impurity elements, and an allowance of zinc. The cutting line has improved mechanical properties and strengthened discharge properties, and can cut irregularly shaped materials or those hollowed in the middle.
