  • Flowable brazing compositions and methods of brazing metal articles together using the same
    Patent number: 10730150
    Abstract: Flowable brazing compositions and methods of brazing metal articles together using the same are provided herein. In an embodiment, a flowable brazing composition includes a non-polymeric carrier medium and flux-coated particles. The carrier medium includes at least one polar organic solvent and is liquid at ambient temperature. The flux-coated particles include a braze material core and a flux coating disposed on the core. The braze material core includes different material from the flux coating. The flowable brazing composition has less than or equal to about 1.5 weight % of polymeric binder components, based upon a total weight of the flowable brazing composition.
    Type: Grant

  • Brazing piece, a method of making a brazing piece, and a method of brazing and components made from said brazing piece
    Patent number: 8871356
    Abstract: The invention relates to a self-fluxing brazing piece. The piece comprises a composite material comprising at least one inorganic material distributed in a metal or metal alloy matrix, the inorganic material forming a flux during brazing to promote the formation of a thermally induced metallic bond. The matrix may be an aluminum silicon brazing alloy and the inorganic material may be a potassium-fluoro-aluminate flux. The piece is made by spray forming.
