Abstract

A dual brazing alloy element for a materially integral connection of a ceramic surface to a metallic surface includes a first layer having a Ni-based brazing alloy with a Ni content of at least 50% by weight and having at least one component configured to lower a melting point of the Ni-based brazing alloy selected from the group consisting of Si, B, Mn, Sn and Ge. A second layer includes an active brazing alloy material having a total content of 1-15% by weight of at least one active element selected from the group consisting of Ti, Hf, Zr and V.
