Abstract:
1. A method for producing composite metal extrusions comprising: loosely arranging in a container at least three metal sheets; at least two of the metal sheets being of a different color; the metal sheets being arranged in an alternating fashion so that the colors alternate; providing voids between at least some of the metal sheets; compressing the metal sheets in the container thereby folding and buckling the metal sheets in at least some of the voids so as to form a billet of distorted multi-colored metal having complex patterns with multi-directional surface orientations; folds of approximately one hundred eighty degrees (180°) in at least some of the metal sheets being formed as a result of the compressing wherein at least some of the metal sheets are folded back upon themselves; and forming an extruded shape by extruding the billet thereby bonding the metal sheets together and forming multi-colored patterns in the extruded shape.
