Abstract

There is provided an aluminum die cast part strength evaluating method is provided for correctly evaluating strength of an actual aluminum die cast part. Strength of the actual aluminum die cast part will be correctly evaluated by conducting ultrasonic inspection of a predetermined range of a high stress region of an aluminum die cast part, which is found out through stress analysis beforehand, for an internal defect, and evaluating that the aluminum die cast part has a predetermined strength if the maximum internal defect area within the predetermined range is equal to or less than a predetermined value. Moreover, an actual aluminum die cast part with a predetermined strength will be evaluated correctly by: evaluating strength using the aluminum die cast part strength evaluating method and setting the maximum-possible internal defect area within the predetermined range of the high stress region to 0.8 mmor less.
