PROBLEM TO BE SOLVED: To provide microwave brazing using a MIM preform. SOLUTION: A method of producing a braze preform (32) for microwave brazing includes providing a mixture of a brazing alloy in metallic powder (34) form and a binder (36), and melting the binder (36) and forming the mixture into a preform (32) having a preselected shape. A method of bonding together two metallic components includes: providing a braze preform (32) comprising brazing alloy in metallic powder (34) form contained in a solidified binder (36); placing the preform (32) adjacent to or within a joint defined between the metallic components; heating the preform (32) using microwave energy to a brazing temperature above the melting point of the perform (32), to cause the brazing alloy to melt and flow into the joint; and allowing the brazing alloy to cool to form a bond between the metallic components.
