In case of Aluminum, filler metal is cladded onto and integrated with the brazing sheet. Filler metal has lower melting point than core material. By heating stacked core to temperature that do not melt core material but melts filler metal, the core is bonded.

*Possible fin pitch and thickness may be adjustable.
**Possible fin pitch and thickness may change depending on size of heat sink.
