1. A susceptor assembly for inductively heating an aerosol-forming substrate, the susceptor assembly comprising a multi-layer susceptor tube defining a cavity configured to receive an induction coil inside the multi-layer susceptor tube, wherein the multi-layer susceptor tube comprises an inner tubular layer, which includes a first electrically conductive material, and an outer tubular layer surrounding the inner tubular layer, which includes a second electrically conductive material, wherein an electrical resistivity of the first electrically conductive material is greater than an electrical resistivity of the second electrically conductive material.
