Abstract

The present invention relates to a multi-layer susceptor assembly for inductively heating an aerosol-forming substrate which comprises at least a first layer and a second layer intimately coupled to the first layer. The first layer comprises a first susceptor material. The second layer comprises a second susceptor material having a Curie temperature lower than 500° C. The susceptor assembly further comprises a third layer intimately coupled to the second layer. The third layer comprises a specific stress-compensating material and specific layer thickness for compensating differences in thermal expansion occurring in the multi-layer susceptor assembly after a processing of the assembly such that at least in a compensation temperature range an overall thermal deformation of the susceptor assembly is essentially limited to in-plane deformations. The compensation temperature range extends at least from 20 K below the Curie temperature of the second susceptor material up to the Curie temperature of the second susceptor material.
