Abstract

PURPOSE: To enhance the damping capacity of a casting by casting a molten Al-Si alloy contg. a specified amount of Si without making proeutectic Si fine.
CONSTITUTION: A molten Al-Si alloy contg. 20W35% Si is cast in a mold without carrying out treatment with phosphorus or the like for making proeutectic Si grains fine. This Al-Si cast alloy is a hypereutectic Al-Si alloy having a structure composed of coarse proeutectic Si having ≥100μm average diameter, Al-Si solid soln. and eutectic Si, and a casting with superior damping capacity can be manufactured.
