Method of making brazing alloy
Abstract
Abstract A method of making a substantially pure brittle brazing alloy in solid form such as sheet or strip consists of forming a paste with an atomized or mechanically powdered alloy and an organic vehicle, continuously applying the paste at a uniform predetermined thickness to a metallic substrate, thermally expelling the organic vehicle from the alloy layer, melting the alloy granules without melting the substrate, and chemically or otherwise removing the substrate. The method preferably is practiced with a continuously moving line which begins with a supply roll of the substrate and ends with a roll of the pure brazing alloy in strip form. This alloy strip may thereafter be blanked or otherwise formed into desired shapes for use as brazing inserts.
