The application discloses a lead-free environment-friendly easy-to-cut zinc white copper, and each component content of the zinc white copper includes Cu: 42-46 wt%, Ni: 12-16 wt%, Mn: 4-6 wt%, Sb: 1.0-2.2 wt%, Fe: 0.01-0.2 wt%, Sn: 0.1-0.5 wt%, and the rest is Zn and inevitable impurities; the structure of the lead-free environment-friendly easy-to-cut zinc white copper includes Mn2Sb phase, the average distribution density of the Mn2Sb phase is greater than or equal to 4000 / mm 2 , and the average distribution density of the Mn2Sb phase with a particle size greater than or equal to 5 mu m is less than or equal to 200 / mm 2 . The zinc white copper has excellent cutting performance, good cold and hot working performance and corrosion resistance under the premise of not using traditional easy-to-cut elements such as Pb, Bi, Si, P and the like, through the synergistic effect of Sb and Mn, Fe and Sn. The application further discloses a preparation method and application of the zinc white copper.
