First off, the first two numbers of an aluminum shaft describe it's diameter which is in 64ths of an inch. The second number is the aluminum shafts wall thickness. A 2212 has a 22/64" diameter with a .012 wall thickness and this a very thin wall thickness. In my case, I'm shooting a target arrow because most hunting shafts start with a .013 wall thickness like a 2213 which has the same 22/64" diameter. A 2020 is a very durable, almost indestructible, arrow. It has a 20/64" diameter, but with a .020 wall thickness. My 2212s are .001" in straightness and it's an Eclipse X7 series aluminum shaft.
My 2212 weighs 8.8 GPI (grains per inch). A 2213 weighs 9.9 GPI (grains per inch). A 2020 weighs 13.5 GPI (grains per inch). So, one can shoot a light arrow, a moderately heavy arrow or a very heavy arrow depending on bow poundage, draw length, point weight and overall arrow length. Aluminum arrows are very easy to tune and I think aluminum is much more easy to tune than a carbon arrow.
Aluminum arrows are very straight, usually .002" in tolerance in the Camo Hunter series and there isn't very much difference in grain weight if you buy 1 dozen or 100 dozen arrows. All the arrows might be plus or minus 1% in weight difference with one another.
Since I've been bowhunting for 47 years, with low poundage bows, I just know what size spined aluminum arrows I can use (shoot) for my 30" draw length with my arrows cut at 32" BOP (back of point). Depending on point weight and brace height, my 42# recurve can shoot a 2114, 2212, 2213, 2215 and 2117 arrow. She doesn't like a 2018 though. My 37# recurve can shoot a 2114, 2212 and 2213 arrow.
I can't equate aluminum to wood so I can't help anyone in that regard. I can't shoot carbon arrows because the correct spined carbon arrow for me, depending on point weight with the low poundage I shoot, is a 500 or 600 series that only come in 30"-31" full length shafts. I can't make a 32" arrow out of a full length 30"-31" carbon shaft.
