The invention provides a metallic composition and methods for making and using the same. In a preferred embodiment the metallic composition forms a conductor path and is bonded to a substrate of aluminum nitride. The metallic composition comprises Mo, Si, Cu and Mn. The Si may be present in the metallic composition as MoSi2. The metallic composition may be produced by firing a paste that has been applied to a substrate of aluminum nitride. The paste comprises an organic vehicle and a metallic powder. The metallic powder preferably comprises about 60% to about 90% by weight Mo, about 0.5% to about 15% by weight MoSi2, about 5% to about 20% Cu and up to about 20% by weight Mn.
