ABSTRACT:
The present invention utilizes a novel flux-coated alloy member that is particularly adapted to be selectively positioned at the braze joints of a tube-and-center type heat exchanger. The flux-coated alloy member is suitably sized and shaped to place a predetermined quantity of flux compound and brazing alloy at the braze joints, so as to avoid the presence of excess flux compound and brazing alloy which may otherwise have a detrimental effect on the quality of the braze joints subsequently formed during a brazing operation. The flux coating of this invention is hard and durable, and is composed of potassium tetrafluoroaluminate particles which are dispersed in either a natural resin or a water soluble epoxy resin.
