Abstract

A laminate aluminum block for forming an article includes a series of aluminum laminate plates to collectively form a tool body for forming an article in a forming operation. A series of aluminum brazing layers are formed for brazing together adjacent aluminum laminate plates. The series of aluminum laminate plates and the series of aluminum brazing layers are deoxidized. Draining apertures are formed through a plurality of the series of aluminum laminate plates. The series of aluminum laminate plates are stacked alternating with the aluminum brazing layers between adjacent aluminum laminate plates without a flux. The stacked series of alternating aluminum plates and aluminum brazing layers are pressed. The stacked series of alternating aluminum plates and aluminum brazing layers are heated in a vacuum furnace to a temperature wherein the aluminum brazing layers braze the aluminum laminate plates together and excess braze material drains from the draining apertures.
