Abstract: A composite metal material displaying lower cost and improved strength and corrosion resistance is shown to comprise a layer of copper or brass material and a layer of aluminum material solidphase metallurgically bonded to respective opposite sides of a layer of low carbon steel. The composite material is formed into an article such as a lamp bulb base or a door knob with the brass or copper layer of the composite material facing exteriorly of the article, the aluminum layer of the composite material then serving as a preferentially corrosive material which protects the low carbon steel layer of the composite material from corrosion.

Abstract: An automotive trim material to be detachably mounted on a painted steel automotive body by means of clips secured to the body is shown to comprise a composite metal laminate material having an outer layer of stainless steel disposed exteriorly of the trim configuration, an intermediate layer of mild steel material, and an opposite outer surface layer of aluminum material, said laminate layer materials being metallurgically bonded together in the solid phase, the stainless steel layer being in scratch-resistant, cold-worked condition, the mild steel layer being in easily formed, annealed condition, and the interface between the mild steel and the aluminum layers being substantially free of embrittling aluminum-iron intermetallic compounds. The composite metal laminate material is formed by roll-squeezing layers of selected metal materials together with reduction in the thicknesses thereof at a temperature below the temperature at which a liquid phase of the layer materials is formed and below a temperature at which intermetallic compounds of aluminum-iron are formed, thereby metallurgically bonding the layers together and cold-working the layer materials. The resulting bonded composite material is then heated to a selected temperature which is above the recrystallization temperature of said mild steel material, which is below the recrystallization temperature of said stainless steel material, and which is below the temperature at which any substantial amount of aluminum-iron intermetallic compound is formed at the bonded interface between the mild steel and aluminum materials of the laminate.

Abstract: Novel and improved metal laminates characterized by low cost, good brazability, and easy formability preferably comparable to low carbon steel, and by high strength and desirable corrosion resistance properties are shown to comprise one or more thin inner layers of corrosion-resistant material of selected tensile strength, yield strength, elongation, and work-hardening properties sandwiched between and metallurgically bonded to relatively thicker outer layers of other less corrosion-resistant metals which are characterized by a relatively lower tensile and yield strengths and by a work-hardening rate at least as low as the metal of the inner layers. Other such laminates having additional outer claddings of solder or brazing materials metallurgically bonded thereto are also shown. In addition, novel and improved tubings are shown which embody such easily formed, corrosion-resistant laminates.

Abstract: A METHOD IS SHOWN FOR ECONOMICALLY MANUFACTURING AN EASILY FORMED AN EASILY BRAZED METAL LAMINATE OF PRECISELY CONTROLLED THICKNESS FOR USE IN MAKING CORROSIONRESISTANT AUTOMOTIVE BRAKE TUBING, THE LAMINATE INCORPORATING A VERY THIN INNER LAYER OF STAINLESS STEEL OF SUBSTANTIALLY UNIFORM THICKNESS SANDWICHED BETWEEN AND METALLURGICALLY BONDED TO OUTER LAYERS OF LOW CARBON STEEL. THE METHOD INCLUDES THE STEPS OF CONTACTING OPPOSITE CLEAN SURFACES OF AN ANNEALED STAINLESS STEEL STRIP WITH RESPECTIVE CLEAN SURFACES OF A PAIR OF ANNEALED LOW CARBON STEEL STRIPS, SQUEEZING THE STRIPS TOGETHER WITH SUBSTANTIAL REDUCTION IN THE THICKNESS THEREOF FOR METALLURGICALLY BONDING THE STRIPS TOGETHER TO FORM A LAMINATE HAVING AN INNER LAYER OF STAINLESS STEEL, AND HEATING THE LAMINATE FOR INCREASING THE STRENGTH OF THE METALLURIGICAL BONDS BETWEEN THE STRIP MATERIALS AND FOR ANNEALING STRIP MATERIALS. THE LAMINATE IS THEN SUBJECTED TO SUBSTANTIAL TENSION BETWEEN TWO SPACED LOCATIONS FOR MINIMIZING THE DIFFERENCE IN RESISTANCE TO COMPRESSIVE REDUCTION WHICH WOULD OTHERWISE EXIST IN THE LOW CARBON STEEL AND STAINLESS STEEL MATERIALS IN THE LAMINATE. THE TENSIONED LAMINATE IS THEN SQUEEZED WITH SUBSTANTIAL FORCE BETWEEN SAID SPACED LOCATIONS TO ACHIEVE SUBSTANTIAL REDUCTION IN THE THICKNESS OF THE LAMINATE MATERIAL, THEREBY TO FORM THE DESIRED THIN INNER LAYER OF STAINLESS STEEL OF SUBSTANTIALLY UNIFORM THICKNESS WITHOUT RISK OF FORMING DISCONTINUITIES IN THE STAINLESS STEEL LAYER WHILE SIMULTANEOUSLY REDUCING THE LAMINATE MATERIAL TO SUBSTANTIALLY THE DESIRED OVERALL THICKNESS. THE LAMINATE IS THEN ANNEALED AGAIN TO PROVIDE THE LAMINATE WITH THE PROPERTY OF EASY FORMABILITY.
