A sprocket assembly, formed of dissimilar materials, includes at least one tooth member made of ferrous material and a circular disk made of a light metal such as aluminum or an aluminum alloy. The circular disk supports the tooth member on an outer peripheral surface thereof. The tooth member is dissimilar-metal welded to the circular disk, either by laser welding or by electronic beam welding. Optionally, multiple individual tooth members may be fitted into notches formed in an outer periphery of the circular disk, and welded therein. A method of making a sprocket assembly is also described.
