Use of a hardenable copper alloy for molds

Abstract

The invention relates to use of a hardenable copper alloy containing 0.1% to 0.5% beryllium and 0.5% to 2% nickel for the production of broad side plates for thin slab continuous casting molds at casting speeds of at least 2 to 6 m/min and higher.

1 . Use of a hardenable copper alloy with content of beryllium of 0.1% to 0.5% and content of nickel from 0.5% to 2% for molds, in particular for production of broad side plates for thin slab continuous casting molds.  
     
     
         2 . Use of a hardenable copper alloy according to  claim 1  for production of broad side plates for thin slab continuous casting molds with casting speeds of at least 2 to 6 m/min.  
     
     
         3 . Use of a hardenable copper alloy according to  claim 1  or  2  with alloying components of 0.1% to 0.5% beryllium and 0.5% to 2% nickel which, with a copper component amounts to at least 99.5%.  
     
     
         4 . Use of a hardenable copper alloy according to one or more of claims  1  through  3  which, except the alloying components of beryllium, nickel and copper, contain maximum 0.5% of impurities.
