Self brazing material and a method of making the material

Abstract

The invention is directed at a self-brazing strip. In an aspect, a process is used to generate a multi-layer alloy strip made up of at least one base layer of with a least another layer of material, that when both the material and base layer are brazed, form an alloy. In an aspect, the other layer of material can include a metal. The base layer can include titanium or a titanium alloy.

What is claimed is: 
     
         1 . An in-situ synthesized brazed product, comprising:
 a base layer of a first material comprising titanium or titanium alloy; and   at least one other layer of a second material comprising copper, nickel, and/or zirconium, wherein the base layer of the first material is bonded to the at least one other layer of the second material, wherein some of the base layer of material is configured to interact with the at least one other layer of the second material upon applying brazing between approximately 1785° F. to 1992° F.   
     
     
         2 . The in-situ synthesized brazed product of  claim 1 , wherein the brazed alloy is formed in-situ during brazing by extracting the first material from the base layer. 
     
     
         3 . The in-situ synthesized brazed product of  claim 1 , wherein the at least one other layer of the second material comprises a plurality of other layers. 
     
     
         4 . The in-situ synthesized brazed product of  claim 3 , wherein the plurality of other layers surround the base layer when bonded. 
     
     
         5 . The in-situ synthesized brazed product of  claim 3 , wherein the product consists of the plurality of other layers and the base layer. 
     
     
         6 . The in-situ synthesized brazed product of  claim 1 , wherein the bonding of the base layer of the first material to at least one other layer of the second material is performed through a cold rolling process. 
     
     
         7 . The in-situ synthesized brazed product of  claim 1 , wherein the in-situ synthesized brazed product is heat treated after the base layer and the at least one other layer are bound. 
     
     
         8 . The in-situ synthesized brazed product of  claim 1 , wherein the first material of the base layer interacts with the second material of the at least one other layer when the base layer and the at least one other layer are heat treated at a temperature of 1200° Fahrenheit or less. 
     
     
         9 . The in-situ synthesized brazed product of  claim 1 , wherein the bonding of the base layer of the first material to at least one other layer of the second material is performed through a hot rolling process. 
     
     
         10 . The in-situ synthesized brazed product of  claim 1 , wherein the brazed product is further cut or formed into parts needed for the ultimate manufactured purpose. 
     
     
         11 . The in-situ synthesized brazed product of  claim 1 , wherein the brazed product forms a foil. 
     
     
         12 . A self-brazing alloy product, comprising:
 a. a base layer of titanium; and   b. at least one other layer of copper, nickel, and/or zirconium, wherein the base layer is bonded to the at least one other layer, wherein upon brazing, some of the titanium of the base layer is extracted and interacts with the at least one other layer to form an in-situ synthesized brazed titanium alloy.   
     
     
         13 . The self-brazing alloy product of  claim 12 , wherein the titanium is extracted and interacts with the at least one other layer when the brazing ranges between approximately 1785° F. and 1992° F. 
     
     
         14 . The self-brazing alloy product of  claim 13 , wherein the at least one other layer comprises a plurality of layers, wherein the plurality of layers surround the base layer. 
     
     
         15 . The in-situ synthesized brazed product of  claim 14 , wherein the product consists of the plurality of other layers and the base layer. 
     
     
         16 . The self-brazing alloy product of  claim 13 , wherein the base layer is bonded to the at least one other layer through a cold rolling process. 
     
     
         17 . The self-brazing alloy product of  claim 13 , wherein the product is heat treated after the base layer and the at least one other layer are bound, the heat treatment done at a temperature at or below approximately 1200° Fahrenheit.
