A METHOD OF PRODUCING COMPOSITE MATERIAL FOR THE MANUFACTURE OF BEARINGS COMPRISING A STEEL BACKING HAVING BONDED TO A FACE THEREOF A FACING LAYER OF HIGH-TIN ALUMINIUM ALLOY WHICH INCLUDES CLEANING THE FACE OF A STEEL STRIP TO WHICH THE FACING LAYER IS TO BE APPLIED, CLEANING BOTH FACES OF A STRIP OF ALUMINIUM FOIL, CLEANING A FACE OF A DUCTILE STRIP OF HIGH-TIN ALUMINIUM ALLOY WHICH IS TO BE BONDED TO THE STEEL STRIP TO FORM THE FACING LAYER, HEATING AT LEAST ONE OF THE STRIPS SELECTED FROM THE GROUP CONSISTING OF HIGH-TIN ALUMINIUM ALLOY STRIP AND THE STEEL STRIP, AND APPLYING PRESSURE, BY ROLLING, SIMULTANEOUSLY TO THE THREE STRIPS WHILE THE HEATED STRIP IS AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 215*C. TO 230*C. AND WITH THE ALUMINIUM FOIL STRIP POSITIONED BETWEEN THE CLEANED SURFACES OF THE STEEL AND THE HIGH-TIN ALUMINIUM ALLOY STRIPS, THE PRESSURE BEING SUCH AS TO BOND THE THREE STRIPS TO ONE ANOTHER TO FORM THE COMPOSITE MATERIAL.
