A low frequency electromagnetic field was introduced into the direct chill (DC) casting process and the ingots of Al-Cu alloy were prepared to study the macrosegregation behaviour of the ingots under the influence of the electromagnetic field.The experimental results showed that there are an obvious positive segregation near to the surface and a negative segregation in the centre area of the ingot.Cu shows the highest segregation tendency among the main elements of Cu, Mg and Mn.
