1. An aerosol-generating article, comprising:
a plurality of elements assembled within a wrapper in the form of a rod having a mouth end and a distal end upstream from the mouth end, the plurality of elements including:
an aerosol-forming substrate disposed at or towards the distal end of the rod; and
a susceptor configured to heat the aerosol-forming substrate,
wherein the susceptor comprises a first susceptor material and a second susceptor material being different from the first susceptor material, the second susceptor material being plated, deposited, or welded onto the first susceptor material,
wherein the susceptor is an elongate susceptor having a length dimension that is greater than a width dimension thereof or than a thickness dimension thereof, the susceptor being disposed in a radially central position within the aerosol-forming substrate, and
wherein the second susceptor material has a Curie temperature that is lower than 500° C.
