Abstract

PURPOSE:To produce sound Al alloy castings having no casting defects by adding specific amounts of Sr and Sb as an Si fining improving agent in a high Si contg. Al alloy having excellent castability. CONSTITUTION:As the titled Al alloy having high Si content and excellent fluidity of its molten metal, the Al alloy contg., by weight, 10.0-13.0% Si, 0.01-0.06% Sr and 0.01-0.06% Sb, contg. the compsn. of 0.5-1.0% Sr ratio or furthermore contg. 0.01-0.2% Bi; or the Al alloy contg. 8.0-13.0% Si, 0.5-1.5% Mg, <=4.5% Cu (particularly 0.8-1.3%), <=0.2% Ti, 0.5% Mn, 0.5-1.5% Ni and contg. 0.01-0.06% Sr and 0.01-0.06% Sb in the ratio of 0.5-1.0 Sb/Sr is used. The aluminum alloy for casting having fined eutectic Si in the presence of Sb and Sr, having improved mechanical characteristics by the addition of Mg, Cu, Ni, etc., and having extremely few casting faults such as shrinkage cavity and pin holes can be obtd.
