The invention discloses a multi-zone heterogeneous material composite structure warm-hot extrusion die. In the die axial direction, a die is divided into a zone with the invariable sectional area anda zone with the reducing sectional area and at the circular bead transition position, the two zones are both prepared by alloy powder through an additive manufacturing technology; the zone with the invariable sectional area is prepared through hot work die steel powder by using the additive manufacturing technology; and the zone with the reducing sectional area and at the circular bead transitionposition is prepared through composite material powder prepared by mixing tungsten carbide or chromium carbide and self-fluxing nature alloy powder. By means of the multi-zone heterogeneous material composite structure warm-hot extrusion die, the comprehensive performance of the die can be improved, the service life of the die can be prolonged, and materials are reasonably used.
