Abstract: ALUMINUM IS CLAD WITH STAINLESS STEEL BY MECHANICALLY CLEANING THE ALUMINUM, HEATING THE METAL SURFACES, IN A HEATING ZONE, TO A TEMPERATURE ABOVE THE RECRYSTALLIZATION TEMPERATURE OF THE ALUMINUM, BRINGING THE CLEANED SURFACE ON CONTACT WITH THE STAINLESS STEEL SURFACE UNDER A PRESSURE TO EFFECT A TWO-STEP REDUCTION OF 5% TO 35% IN EACH OF THE METALS. A 0.25% TO 2.0% REDUCTION IS ACCOMPLISHED IN THE FIRST STAGE, OUTSIDE THE HEATING ZONE, WHILE THE METALS ARE ABOVE THE RECYRSTALLIZATION TEMPERATURE WITH THE REMAINDER IN THE SECOND STAGE. A DIFFUSION BOND IS FORMED AND THE BONDED METALS ARE ANNEALED AT 700*F. TO 900%F.
