Abstract
Magnesium alloys are disclosed for diecasting with reduced defects comprising aluminum in an amount greater than or equal to about 10 wt % and less than and equal to about 15 wt %; zinc in an amount greater than 0 and less than or equal to about 0.5 wt %; silicon in an amount greater than 0 and less than or equal to about 1.5 wt %; and the balance being magnesium and unavoidable impurities. Magnesium parts diecast from these magnesium alloys are also disclosed.
