Abstract : Use of acceptable aging treatments on the basis of processing and chemistry permits attainment of near optimum physical properties for aluminum shell castings. Data developed on aging times for one aluminum casting alloy or one casting process are not always applicable to another aluminum casting alloy or process. A wide range of aging times and temperatures will produce near optimum properties for 356 aluminum with less than .30% iron. However, the acceptable aging cycle, time and temperature ranges narrow rapidly for iron contents of over .40%. (Author)
