If I was going to buy aluminum cranks, would they be weak? Are aluminum cranks strong enough to take dirt and park abuse?

if you take a tube of aluminum and hit it on the ground would it bend easier than a tube of steel? if you don't know the answer its yes. go with the chromo

Yeah they'll be fine. Obviously Aluminium is weaker but there's a lot more material on Alloy Cranks.

Aluminium Cranks aren't tubular though.
In order to truly find out, there would have to be a stress to yield test. First off, with aliminum, the series aluminum makes a difference, as well as what it's hardened to. (T-3/T-6, etc) if a set of those were made out of 0, they would bend a little every time you hopped or jumped anything.
With 4130 crank arms, obviously thickness and heat treatment means a lot, as well as quality of the weld. (Was it welded on the Monday morning following Superbowl Sunday) A welder may say that his hungover welds are the same, because he uses the exact same settings, but not all welders take their job as seriously as others. I would love to see a "battle of the cranks" with every brand BMX crank on the market, with both a test that just pushes them to snap and recorded the force needed, and then a series of tests that takes rider weight into consideration when they are flexed repeatedly like the Odyssey R series forks.
If I were independently wealthy, that would be exactly what I would do. As a matter of fact, I would write each company and ask them if they're willing to submit their components to get a certain certification or rating. It would be free of charge, but would let riders know what parts are certified instead of having to make threads on the Internet. Wait, who am I fooling. You know damn well it wouldn't stop even one thread, haha.
There could even be a wear through test for grips, as well as a test to see which ones get slippery when wet with a saline solution.

unless your buying primo powerbites (aluminium) otherwise buy cromoly cranks
don't overthink it just do it !
I am buying shadow noctis, which are aluminium, people say that they are improved primos. I will do a review since there arent lots of it in internet.

Wait for the new Eclat Maverick cranks. I believe they're aluminum and they have no welds , just cold forged which makes them stronger. And it has a press on pedal thingy that makes it from stripping or coming out

But most aluminum cranks are really expensive.
You say BMX is your life but you barely ride.
BUT hey, That's none of my business.
They are the same prices here, well, animals and odysseys are more expensive.

IF you do crank arm grinds, get chromoly. Alloy tends to stick to steel, meaning you won't slide far, you will stop abruptly.
If not, get whatever floats your boat. The Shadows are similar to Powerbites/Hollowbites AND some classic GT alloy cranks that lasted forever.
Very solid. If you do crank arms, get chromo.

I ride the shadow noctis. Very strong cranks. No bend at all.
