Micro-alloyed oxygen-free copper alloy and its use

Abstract

An oxygen-free copper alloy comprising oxygen-free copper and, micro-alloyed therein, about 1-250 ppm tin (Sn) and/or about 1-150 ppm manganese (Mn). The invention also relates to the use of said copper alloy.

1 . An oxygen-free copper alloy, characterized in that said alloy comprises oxygen-free copper and, micro-alloyed therein, about 1-250 ppm tin (Sn) and/or about 1-150 ppm manganese (Mn) in order to improve the weldability of the alloy.  
     
     
         2 . A copper alloy according to  claim 1 , characterized in that said copper alloy comprises tin (Sn) 1-120 ppm, preferably 10-30 ppm.  
     
     
         3 . A copper alloy according to  claim 1  or  2 , characterized in that said copper alloy comprises manganese (Mn) 1-70 ppm, preferably 5-20 ppm.  
     
     
         4 . A copper alloy according to any of the claims  1 - 3 , characterized in that the electroconductivity of said alloy is over 100% IACS.  
     
     
         5 . A copper alloy according to any of the claims  1 - 4 , characterized in that the electroconductivity of said alloy is over 101% IACS.  
     
     
         6 . The use of a copper alloy according to any of the claims  1 - 6  as conductor strip.  
     
     
         7 . The use of a copper alloy according to any of the claims  1 - 6  as tubular wire in conductor cables, such as coaxial cables.  
     
     
         8 . The use of a copper alloy according to any of the claims  1 - 6  in weldable conductor arrangements.  
     
     
         9 . The use of a copper alloy according to any of the claims  1 - 6  in weldable and workable conductor arrangements.  
     
     
         10 . The use of a copper alloy according to any of the claims  1 - 6  as tubular wire in underwater cables.  
     
     
         11 . The use of a copper alloy according to any of the claims  1 - 6  in corrugated tubes.
