THE METHOD OF MAKING A BIMETALLIC BEARING WHICH COMPRISES: SELECTING A LAYER OF ALUMINUM ALLOY COMPRISING AT LEAST 5% LOW MELTING POINT CONSTITUENTS AND SELECTING A STEEL BACKING LAYER; CLEANING AND BRUSHING THE BONDING INTERFACE OF SAID LAYERS; PREHEATING AT LEAST SAID LAYER OF ALUMINUM ALLOY TO A TEMPERATURE WITH THE RANGE OF 700* TO 800*F.; SUBSTANTIALLY IMMEDIATELY THEREAFTER AND WITHOUT AFFECTING ANY APPRECIABLE TEMPERATURE DROP; PASS ING SAID LAYERS TOGETHER THROUGH PRESSURE ROLLS HAVING A TEMPERATURE BETWEEN 200* TO 350*F. TO COMBINE SAID LAYERS FACE TO FACE WITH EACH OTHER AND TO REDUCE THE THICKNESS OF EACH LAYER TO EFFECT A STRONG METALLURIGICAL BOND THEREBETWEEN; CUTTING SAID LAYERS INTO SECTIONS; AND DEFORMING SAID SECTIONS INTO SUITABLE BEARING SHAPES.
