Aluminum will weigh 5 x the mahogany? Wow.


Specific gravity of Aluminum = 2.7
Specific gravity of Mahogany = ~.5

What's the cost difference between aluminum and wooden props?


New Ed Sterba Birch prop ~ $600. New Sensenich Aluminum $2,000. These are
rough figures.

Why do people buy birch instead of mahogany?


Birch has a specific gravity ~ .7 and is a lot stronger per pound than
Mahogany when used for a prop.

Might go to a wood prop if the one I have doesn't work out. But it is quite
a good prop, and it's absolutely gorgeous, to boot!
