ABSTRACT:
A clad brazing filler for use in bonding a ceramic to a metal, glass or another ceramic having a substantially different thermal expansion coefficient, and composites using such a filler. According to one aspect of the invention, a brazing filler of a clad type is provided which is composed of a titanium layer adjacent a silver, copper or silver-copper alloy layer, or a combination of silver and copper layers, with the titanium content being in a range of 3 to 80% of the total weight of the layers of the assembly. In accordance with another aspect of the invention, a brazing filler of the clad type is provided which combines the layer arrangement of the first aspect with either a layer of a metal having a low thermal expansion coefficient, a layer of a metal having a low Young's modulus, for a combination layer of both, arranged in any order.
