1. A compressor wheel for a compressor of a turbocharger, the compressor wheel comprising a hub and a multiplicity of blades on the hub, wherein in intermediate spaces of the multiplicity of blades a channel is in each case formed between a suction side and a pressure side, the channel configured to guide fluid that flows in axially in relation to a rotation axis and further configured to guide fluid radially or radially-axially outward, wherein the hub in relation to the rotation axis in at least one channel is contoured with a rotationally symmetrical portion and a non-rotationally symmetrical portion, wherein the non-rotationally symmetrical portion has a region of modified thickness configured to be tangential to the rotationally symmetrical portion and is formed by radii that are variable in the flow direction, wherein the non-rotationally symmetrical portion of the hub begins at the external periphery of the hub and extends radially inward, and a transition region embodied as a radiused connection between the hub and the suction side of the blade adjoins the non-rotationally symmetrical portion.
