<p>The present invention relates to a high-strength, lightweight zinc-aluminum alloy for die-casting, and more particularly, to a high-strength, lightweight zinc-aluminum alloy for die-casting which can be used for die-casting and made lighter and stronger than conventional zinc alloys (e.g., ZA27) by adding a suitable amount of an additive, in order to replace zinc alloys (e.g., ZA27) which have been used as a die-casting alloy for forming exterior materials for notebook computers or mobile phone cases or for forming parts such as hinges. For this purpose, the present invention relates to an alloy for die-casting, comprising: 2.0 wt % or less (but more than 0) of silicon (Si); more than 1.4 wt % but not exceeding 9 wt % of copper (Cu); 27-70 wt % of aluminum (Al); with the remainder being zinc (Zn) and unavoidable impurities.</p> |
