ABSTRACT:
A master alloy compacted mass of particulate metal is fabricated using non-spherical particulated aluminum, such as aluminum sawdust from production operations, in combination with metal particles of a brittle and friable principal metal of the master alloy which is non-malleable and, therefore, non-compactable. The compacted mass retains its homogeneity by the interlocking action of the aluminum sawdust and thereby obviates the need for additional binder despite the non-compactability of the metal particles of the non-malleable principal metal of the master alloy.
