But cast aluminum is stronger than cast iron. Not sure why that is so hard to understand. Pound for pound, cast aluminum is stronger than cast iron. The only reason why Lee is using cast iron now is that they can get it cheaper and with less defects from China and they can get away with steel on steel wear points and not need bushings. It is a cost issue to Lee. This design approach is why Lee can sell a best in class Turret press for less than an RCBS Rockchucker.
