A master alloy for modifying the eutectic phase of aluminum silicon casting alloys consisting of 10 to 70 % strontium, preferably 20 to 60 % strontium, 5 to 60 % magnesium, preferably 5 to 40 % magnesium, and 5 to 60 % aluminum, preferably 5 to 40 % aluminum. The alloy can be used for modifying the aluminum-silicon eutectic phase of hypoeutectic, eutectic and hypereutectic aluminum-silicon based casting alloys.
