The eutectic structure of hypoeutectic Al-Si alloy shows a modified structure when the amount of P is small, and an unmodified structure when the amount is large. We, therefore, developed a de-phosphorus treatment method which combines flux processing with rotary degassing processing to obtain the modified structure. Through this method, the amounts of gas, inclusions, as well as P could be reduced.
