The rotor includes a certain number of blades (12) which extend in a spiral from a rotary central hub and which include, viewed in the direction of rotation, a leading edge (16) substantially perpendicular to the direction of rotation. Each blade (12) is a bimetallic cast element most of the leading edge (16) of which consists of an insert (18) made of an alloy having good resistance to wear which is supported by a more ductile base alloy, the connection between the two alloys being a mechanical connection achieved by clinching the two alloys together. Application to paper pulp mixers.
