ABSTRACT:
An aluminum-silicon alloy having excellent mechanical characteristics is formed by pressure casting of a molten material concurrently with modifying thereof by a flux which includes at least one element selected from the group of Na, Sb, Sr, and/or Ca, allowing a substantially fine grain of silicon to be dispersed in the alloy. Alternatively, the step of the pressure casting is replacable by substantial uniform cooling of the molten material regardless of a thickness thereof by cooling a die having a mold formed of a Cu-W type material, which mold corresponds to a substantially thick portion of the alloy.
