I'm not arguing, but is that true?
What I've found so far is that the density of Al is 0.098lb/in^3 (approx
1.56 oz/in^3 and that white ash is 41 lbs/ft^3, which should work out to about 0.379 oz/in^3, unless my math is completely f'd. I got some of the info from here;
Does Ash float?
Aluminum doesn't...
Duh! OK, but my ash doesn't float :).

Well then, you might be in the ball park!

Most woods float. Does aluminum?
Well, 1.56 is greater than 0.379, so I'd have to say aluminum is much denser than ash, by a factor of about four.
You made the math more complicated than it needed to be, but your results are correct: aluminum is much denser than ash.
Simpler version: Aluminum 0.098 lb/in^3 * 1728 in^3/ft^3 = 169 lb/ft^3 Ash 41 lb/ft^3

Well, lignum vitae (ironwood) doesn't float. Neither does knobthorn or some of the rosewoods (Dalbergia sp.). There are a lot of woods that are so dense they don't float. Wikipedia says the density of lignum vitae is between 1.28 and 1.37 grams per cubic centimeter. Aluminum (from wikipedia) has a density of 2.70 gr/cc. Titanium = 4.5 gr/cc. Iron = 7.87 gr/cc. Lead = 11.34 gr/cc. Gold = 19.3 gr/cc Uranium = 19.1 gr/cc Balsa = 100-200 kg/cubic meter (you do the math).
