Abstract

The present invention addresses the problem of providing an aluminum alloy cast impeller for compressors which stably shows high- temperature strength when used at temperatures around 200ºC and which has excellent manufacturability. This Al alloy cast impeller for compressors has a configuration comprising a boss part , a plurality of blade parts, and a disk part. The Al alloy cast impeller for compressors is constituted of an Al alloy containing 1.4 -3.2 mass% (hereinafter , referred to as '%') Cu, 1.0 -2.0% Mg, 0.5- 2.0% Ni ,0.5- 2.0% Fe , and 0.01- 0.35% Ti. The boss part, the blade parts, and the disk part have secondary dendrite arm spacings of 20- 50 µm, 10- 35 µm , and 5- 25 µm , respectively. The impeller satisfies the relationship Amax>Bmax>Cmax where Amax , Bmax , and Cmax respectively are the maximum secondary dendrite arm spacings of the boss par,t blade parts , and disk part and has a 0.2% proof stress at 200ºC of 260 MPa or higher. Also disclosed is a process for producing the Al alloy cast impeller.
