Abstract
In order to reduce iron content in aluminum alloys, a technique has been tried to segregate and separate intermetallic compounds containing iron by applying centrifugal force during solidification. The castings solidified under centrifugal force have shown obvious macroscopic segregation. The iron content decreases in the inner part of cast ingot from 2.07 mass% to 0.27 mass% due to the centrifugal force and the reduction ratio of iron has reached 87%. Thus, the utilization of this segregation phenomenon is a possible way of removal of the iron in aluminum alloys.
