Method for making bi-metallic members

Abstract

A method for making bi-metallic members includes the steps of anodizing aluminum coming off of a coil, providing a metallic outer ring member having an inner hollow section by using a die to punch out the member off of the coil, providing a metallic inner core member by using a die to punch out the member off of the coil so that its shape fits within the inner hollow section of the metallic outer ring member, inserting the metallic inner core member into the inner hollow section of the metallic outer ring member so as to form a bi-metallic member, stamping the bi-metallic member to thereby hold the metallic inner core member and the metallic outer ring member together.

1 . A method for making bi-metallic members consisting in the steps of:
 a. anodizing aluminum coming off of a coil;   b. providing a metallic outer ring member having an inner hollow section by using a die to punch out metal from said coil so as to create said metallic outer ring member;   c. providing a metallic inner core member by using a die to punch out metal from said coil so as to create said metallic inner member which is configured and sized so as to fit inside said metallic outer ring member;   d. inserting said metallic inner core member into said inner hollow section of said metallic outer ring member so as to form a bi-metallic member;   e. stamping said bi-metallic member to thereby hold said metallic inner core member and said metallic outer ring member together.   
     
     
         2 . The method of  claim 1  wherein an engraved image upon the surfaces of said metallic inner core member and said metallic outer ring member is created, to thereby provide an identifying image upon said bi-metallic member. 
     
     
         3 . The method of  claim 1  wherein metals other than aluminum use a plating process. 
     
     
         4 . The method of  claim 1  wherein metals other than aluminum use a cladding process. 
     
     
         5 . The method of  claim 1  wherein metals other than aluminum use an alloy material.
