A brazing paste for brazing together materials having dissimilar thermal expansion rates which includes a powdered metal brazing alloy, powdered metal spacer spheres, an inorganic flux and a binder material. The spacer spheres are ductile metal which is not drawn into solution by the brazing alloy during the brazing operation and thereby provides a buffer which absorbs thermal stresses generated by the different materials upon cooling the joint. The brazing paste according to the present invention is equally well suited for brazing operations using directly applied heat, for example torch or induction. |
