You may be right on all your technical info but the true reason a SS prop
outperforms an aluminum one is due to blade design/shape. Not thickness.
SS props have a rake and can have bow lift and/or tail lift in them based on
the design. You can't achieve these kinds of shapes w/ aluminum and it hold
together.


Agreed Tony the alloy "could" achieve a blade shape the same as the
s/steel blades, but to be strong enough it would be too thick & the
extra primary drag would negate the benefits of the better blade shape.
