PROBLEM TO BE SOLVED: To provide a flux for casting having high fluidity and suitable for casting, particularly, for casting a composite cast body.SOLUTION: A flux for casting a composite cast body includes, by mass, 10 to 25% SiO, and the balance NaO with inevitable impurities. The flux for casting a composite cast body includes, by mass, 10 to <20% SiO, and the balance NaO with inevitable impurities. The flux for casting a composite cast body can include >0 to 25% BOas well. The flux for casting a composite cast body can include >0 to 15% LiO as well. |
