Are you sure? Methinks cast aluminum may be stiffer than steel, as it will
break, as opposed to bending like steel.

Just thinking out load.

Negative... the cast will flex more as well as being easier to break if
struck. That's (in part) why SS props can be made with thinner blades and
tend to perform better - because of the thinner blades.
