A composite body, comprising an annular liner (2) and a shell (3) cast on this liner, the liner (2) comprising a first material and the shell (3) comprising a second material which has a higher thermal expansion coefficient and a lower melting temperature than the first material, the liner (2) having an outer lateral surface (9) and an outwardly directed end surface (10) extending radially inward from said lateral surface (9), and the shell (3) being cast in one piece on the lateral surface (9) and the end surface (10). The liner (2) comprises a flange (11) which extends axially from the end surface (10) and is arranged radially inside said lateral surface (9) and against which the shell (3) is cast. |
