The invention relates to the field of copper-nickel alloys, in particular to a corrosion-resistant white copper tube and a manufacturing method thereof. The corrosion-resistant white copper tube comprises the following chemical components in percentage by weight: less than or equal to 0.03 percent of C, 0.10-0.20 percent of Si, 6.0-8.0 percent of Mn, less than or equal to 0.005 percent of S, 0.15-0.20 percent of P, 22.0-24.0 percent of Ni, 2.0-4.0 percent of Co, 2.0-4.0 percent of Zn, 0.20-0.40 percent of Pb, 3.0-4.0 percent of Fe, 0.15-0.20 percent of RE, 0.005-0.010 percent of As and the balance of Cu. The method comprises the following steps: manufacturing a white copper tube blank by performing induction smelting; performing coil stretching production on the white copper tube blank through the procedures of casting, sawing, water seal extrusion, tube rolling, disk stretching, disk blade die peeling, disk stretching, stretching by using a Schumag combined pulling machine, straight bar stretching and annealing. By adopting the corrosion-resistant white copper tube, the problems of limited service life of the conventional copper-nickel alloy material and non-adaptability to coil stretching production due to poor elasticity are solved, and coil stretching is realized.
