Aluminum alloy for die casting, and aluminum alloy die-cast product using same

Abstract

Provided are: an aluminum alloy for die casting, having castability and mechanical properties equivalent to those of ADC12 and corrosion resistance equivalent to that of ADC6; and an aluminum alloy die cast obtained through die-casting the alloy. Specifically, the present invention is directed to an aluminum alloy for die casting that contains: Cu by not more than 0.10 wt %; Si by 12.0 to 15.0 wt %; Mg by not more than 1.00 wt %; Fe by 0.05 to 1.00 wt %; Cr by 0.10 to 0.50 wt %; and a remaining portion thereof being Al and unavoidable impurities.

1 . An aluminum alloy for die casting comprising: Cu by not more than 0.10 wt %; Si by 12.0 to 15.0 wt %; Mg by not more than 1.00 wt %; Fe by 0.05 to 1.00 wt %; Cr by 0.10 to 0.50 wt %; and a remaining portion thereof being Al and unavoidable impurities. 
     
     
         2 . The aluminum alloy for die casting according to  claim 1 , wherein at least one selected from Na, Sr, and Ca is added by 30 to 200 ppm. 
     
     
         3 . The aluminum alloy for die casting according to  claim 1 , wherein Sb is added by 0.05 to 0.20 wt %. 
     
     
         4 . The aluminum alloy for die casting according to  claim 1 , wherein Ti is added by 0.05 to 0.30 wt %. 
     
     
         5 . The aluminum alloy for die casting according to  claim 1 , wherein B is added by 1 to 50 ppm. 
     
     
         6 . An aluminum alloy die cast obtained through die-casting the aluminum alloy for die casting according to  claim 1 .
