steel vs aluminium Co2 tank?

Hey guys I did a quick search but did not find much...

so any pros and cons of steel vs aluminum tanks I should know of? shopping around for a 10# tank.
found a OK price on the recert. steel tanks...so before I decided I though I would ask the community.

cheers

Only things I can think is the weight and possible rust with the steel tanks.

Just starting out

Aluminum is much more resistant to CO2 than steel, at least if water is present..
"Dry" CO2 isn't as corrosive to steel.

Actual criticality is disputed..
Few fire extinguishers are aluminum.. for what that is worth..

Al def. is lighter...

I don't think it matters much, IME. I never had rust cause any issue with my reg/solenoid in 10 years time. I have swapped a lot of tanks too. I get steel tanks swapped out quickly instead of waiting for someone to refill a tank. Prices may reflect the labor of getting it filled too. It also depends on your local beer/welding shops as to how much this will be. My welding supply shop will only swap out 5# and 20# tanks of CO2, so that's something you might want to consider as well.

If you're stuck having to "display" your tank (wont fit in the stand; cant hide anywhere else) then the aluminum are usually prettier to look at.

I was told by the welding supply shop that steel is being phased out in favor of aluminum. No idea how true that is but weight is really the only difference that I know of. Just ask for the last hydro test date so you'll know if you need to get one done. Costs extra at some places.

so It looks like I can exchange tank at a welding shop or fill my own at a gas place. the welding shop was rushing to lunch so he would not tell me prices just to come in...I am not sure how the exchange works if you dont have one to exchange? guessing they will have you buy/rent one of theirs?

how does that work.

You just purchase one from them and swap it for another pre-filled tank when that one is empty. Just like purchasing a propane tank for your grill.

I live near Austin, Tx so there are lots of wanna-be bands that start and then fail so there is almost always somebody selling off the CO2 tanks they have tried to use for the "smoke" so that leaves a lot of used tanks of all sorts showing up on the local ads. So I just buy up the cheapest used and do the swap at the local welding gas shop. They do not care whether it is steel or AL as long as it is in decent shape.
Two ways to look at which is better, perhaps. The aluminum can look nicer if that counts big but for lots of folks the tank is just another tool and how it lasts is more important. Where the tank just sets somewhere and pushes gas, the material matters very little but if you are doing rough work and dragging a tank around, steel is much more durable. Lots of tanks get thrown in the back of a truck or dropped off a roof so steel fits them better!
For our use, either is good.
