The density of aluminum is 0.0975 lb/in³. Multiply that by the volume of the
piece in question and you have your answer. In this case, a 3 inch diameter
bar 6 inches long would weigh:

0.0975 x (pi x r² x h ) = 0.0975 x (pi x 1.5² x 6) = 4.14 lbs.

Hi All,

I was wondering, does anyone know if old car wheels would be good
aluminum, either to cut from, or to cut up and melt down. I was just
buying new tire the other day, and noticed all kinds of old rims
piled up out back of the shop. I thought if I could cut them up, I
could melt them down for small castings.

Anyone tried this, or know what they are made from.

Rob,
I saw something about this in the hobbicast group a little while
back. I think that a couple of people said that you can use
sandpaper to make a clean spot, then pour vinegar on it. Magnesium
turned black, but aluminum stayed silver. I don't remember the
details, and I might have it backwards, check their archive and I'm
sure you'll find the answer.
