  • Patent number: 6068176
    Abstract: A brazing transfer alloy tape which includes a carrier layer that may be easily seen by the operator so that it may be removed before brazing is provided. The brazing tape consists essentially of a brazing alloy layer having two opposing surfaces, a pressure sensitive adhesive disposed on one of the two opposing surfaces of the brazing alloy layer for adhering the brazing tape to the object to be brazed, a backing layer disposed on the pressure sensitive adhesive, and a visually distinctive carrier layer attached to the other of the two opposing surfaces of the brazing alloy layer opposite the pressure sensitive adhesive. The carrier layer is such that it is easily noticeable by an operator before brazing. This is accomplished, for example, by forming the carrier layer from a colored or opaque material, or from a material having a visually distinctive pattern.

  • Patent number: 4477527
    Abstract: A stable, mechanically formed brazing shape comprising a polymer matrix which may be composed of thermosetting and thermoplastic resins in various combinations and braze alloys or compounds which when formed by extrusion, dried, and cured is able to replace brazing pastes, loose powders and tapes in many brazing applications especially those requiring the deposition of a uniform amount of alloy in the brazed or bonded joint. The fabrication of shapes of various cross sections by extrusion is also described.
