Composite materials are composed of a primary metallic base material, such as a titanium metallic material, metallurgically bonded to one or more secondary materials having desirable thermal conductivity properties and having a coefficient of thermal expansion ("CTE") that generally matches the CTE of the primary metallic material. An exemplary composite material is composed of a titanium primary material metallurgically bonded to a secondary metal matrix composite material having a high thermal conductivity, such as aluminum silicon carbide. Methods for manufacturing such composite materials are disclosed.

[ We claim:] [1.]1. A composite material comprising:a primary metallic base material forming a primary metallic structure having one or more recesses, wherein the primary metallic base material has a first thermal conductivity and a first coefficient of thermal expansion (CTE);a secondary material disposed within the one or more recesses of the primary metallic base material, wherein said secondary material has a second thermal conductivity higher than the first thermal conductivity and a second CTE that substantially matches the first CTE.
