High-carbon steel wire rod with diameter smaller than or equal to 6.5 mm and excellent bending capacity and production method

A high-carbon steel wire rod with the diameter smaller than or equal to 6.5 mm and excellent bending capacity comprises chemical components including, by weight, smaller than or equal to 0.012 wt% of P, smaller than or equal to 0.009 wt% of S and smaller than or equal to 0.095 wt% of Cu under existing components in the field of steel grades. The production method comprises the following steps: after smelting and casting into a blank, heating the casting blank; rolling is conducted; spinning is conducted; cooling is performed; and after air cooling to room temperature, bundling and packaging are carried out. On the premise that the mechanical property is guaranteed, the performance is uniform and stable after 15-day aging, the segregation of a wire rod is smaller than or equal to 2.0 level, no obvious softening zone exists on the section, and the volume ratio of pearlite in a metallographic structure is not lower than 80%; the elongation is greater than or equal to 9.0%, the area reduction is greater than or e
