Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
175 words
THE METHOD OF MANUFACTURING CLAD BERYLLIUM-COPPER WHICH COMPRISES APPLYING TO A SUBSTANTIALLY OXIDE-FREE SURFACE OF A BAR OF BERYLLIUM-COPPER A COATING OF A METAL (A) HAVING A MELTING POINT ABOVE 1350* F., (B) THROUGH WHICH BERYLLIUM DOES NOT READILY DIFFUSE, (C) THE EUTECTIC OF WHICH WITH BERYLLIUM HAS A MELTING POINT ABOVE 1350* F., AND (D) THE OXIDE OF WHICH IS EASILY FLUXED, SANDWICHINGG SOLDER HAVING A FLOW POINT BETWEEN 1100* F. AND 1450* F. BETWEEN SAID COATING AND A LAYER OF CLADDING METAL, AND SUBSTANTIALLY UNIFORMLY HEATING THE SANDWICH AT A TEMPERATURE ABOVE THE FLOW POINT OF THE SOLDER, BUT BELOW 1475* F., AND UNDER SUBSTANTIAL PRESSURE FOR A SUFFICIENT PERIOD OF TIME TO EFFECT COMPLETE CONVERSION OF THE SOLDER BY DIFFUSION WITH THE ADJACENT METALS TO AN ALLOY HAVING A MELTING TEMPERATURE SUBSTANTIALLY ABOVE THE INITIAL FLOW POINT OF THE SOLDER AND ABOVE ABOUT 1350* F., THE DURATION OF THE HEATING BEING SUCH THAT THERE IS NO SUBSTANTIAL AREA WHERE DIFFUSION HAS MODIFIED THE COMPOSITION OF THE COATING METAL THROUGHOUT ITS ENTIRE THICKNESS.

Claim 3
Dependent Claim
150 words
SOLUTION-ANNEABLE COMPOSITE METAL STOCK COMPRISING A BASE OF BERYLLIUM-COOPER, A LAYER OF AN INTERLINER METAL HAVING ONE FACE BONDED TO THE BERYLLIUM-COPPER BASE, SAID INTERLINER METAL BEING ONE (A) HAVING A MELTING POINT ABOVE 1350* F. (B) THROUGH WHICH BERYLLIUM DOES NOT READILY DIFFUSE, (C) THE EUTECTIC OF WHICH WITH BERYLLIUM HAS A MELTING POINT ABOVE 1350* F., AND (D) THE OXIDE OF WHICH IS EASILY FLUXED, AND A LAYER OF CLADDING METAL SECURED TO THE OPPOSITE FACE OF THE LAYER OF INTERLINER METAL, THE INTERFACIAL PORTIONS ONLY OF THE INTERLINER METAL AND THE CLADDING METAL HAVING INTERDIFFUSED THEREIN THE METAL COMPONENTS OF A SILVER SOLDER HAVING A FLOW POINT BETWEEN 1100* F. AND 1450* F. AND FORMING THEREWITH INTERFACIAL ALLOYS HAVING A MELTING POINT ABOVE THE SOLUTION-ANNEAL TEMPERATURE OF THE BERRYLIUM-COPPER, WHEREBY A PORTION OF THE INTERLINER METAL UNMODIFIED BY DIFFUSION SEPARATES THE CLADDING METAL FROM THE BERYLLIUM-COPPER BASE.
