The invention relates to a composite atomizer for manufacturing gas atomization quick-coagulation spherical superfine metal powder, which comprises a crucible for containing metal liquid and an atomizer stationing chamber which is arranged around a metal liquid guiding pipe at the bottom of the crucible, is communicated with a high-speed airflow source and has an annular structure. The composite atomizer is characterized in that: inner and outer nozzle rings which are formed by a plurality of nozzles arranged in a mode of uniform distribution and have structures of concentric circles are formed around the annular bottom surface of the atomizer stationing chamber, and the nozzles are arranged in a skew mode which makes the axes of the nozzles intersected with the lower extended line of the axis of the liquid guiding pipe, wherein the axes of all nozzles on the inner nozzle rings close to the axis of the liquid guiding pipe and the axis of the liquid guiding pipe intersect at a vertical angle point alpha 1 in an atomizing area II, the axes of all nozzles on the outer nozzle rings away from the axis of the liquid guiding pipe and the axis of the liquid guiding pipe intersect at a vertical angle point alpha 2 of an atomizing area III, and the distance between the two vertical angle points is between 0.1 and 0.4 millimeter; and the atomizing pressure is controlled to be between 0.5 and 2.5 MPa.
