What are the advantages/disadvantages I should know when choosing between brass and aluminum?

It seems that most people here like to use brass, but I'd like to know why. I'm placing a large order on McMaster and aluminum is a heck of a lot cheaper. I'm not opposed to ordering the brass if it's significantly better in terms of performance, but I can think of a lot of things that I'd like to do with the money I'd save on the aluminum.
Jose, can I have permission to fire?

The reason brass is much favored for a barrel replacement is because it comes in such small increments. You can find a good fit for your darts, since they come in increments of 1/32. Aluminum comes in very little sizes and I think it's a bit heavier due to thicker walls. I've never used aluminum before, but I know several people have. Go to the store and see how well your darts fit in aluminum. If it's a nice fit, then great, aluminum will work for you.

I might as well share this discovery. I found some aluminum structural tubing in the mcmaster catalog that has the same ID as 9/16" brass, 1/2" CPVC, and PETG. It's also fairly cheap (compared to brass).
1658T49 - Alloy 6063 Aluminum Round Tube .625" OD, .527" ID, 8' Length = $7.41 Each

It's pretty thick so it's durability should be excellent. Just as smooth as brass, but should prove easier to work with and won't tarnish. The outer diameter is 5/8".
I plan to use it in some in some upcoming projects.

Sorry for the retarded post, but could you link us to that tubing? I searched mcmaster and I didn't see it...

I assume that we could substitute this aluminum in mods like FA24's Longshot. I don't see why the performance would be any different.

Forsaken Angel's Lonshot mod had to use brass. Unless the aluminum Has increment sizes that small, it won't work because they won't slide over eachother for that perfect seal.

The aluminum wouldn't be useful for FA24's method since that relies upon the bolt face sliding over the receiver. You would have to find an alternative arraignment (which would probably require lathe work) in order to use aluminum.

I can't directly link to anything in the Mcmaster catalog. Search for part# 1658T49

Right. Didn't think about that...

However, the aluminum would be useful for the barrel of, say, a Crossfinder?

It would be useful for anything where you want a very durable long barrel. I mean, if you compare it cost wise to CPVC you get

5 feet of 1/2" SCH80 CPVC = $ 6.51
8 feet of aluminum tube (.527 ID .625" OD) = $7.41

So for an extra dollar you get three more feet, plus it will look much cooler and be easier to drill mounting holes for since it's 5/8" OD.

Yeah, aluminum is hard to find up my way. Brass is pretty easy to find in the larger towns/small cities, but PETG is really hard to find, it seems that most pet suppliers won't carry it. One store showing promise is primarily into aquatic pets, so for anybody out there looking for some local PETG, check pet stores with alot of aquatic life.

PETG is not going to be available in usable sizes unless you order a custom run of 100 feet or more. Hence why it's sold on the forums here and elsewhere by certain members. If you want to use PETG contact me, OMC, or sometimes cxwq.

Again, those are not usable sizes because their dimensions are precisely fractional (1/2" ID won't work). Typically a barrel will need somewhere between a .525" to .5345" inner diameter to be compatible with micro stefans.

dude, are you gay!!!?!!???! now you made me forget what i was about to say.....



oh!!! thanks cxg.. although i can get your name staright you helped me alot. i am using homemade stefans, and let me tell you what works best for my nite finder...

BRASS

EDIT: the big thing that i don't get is that modman uses brass barrels and it gives the nite finders the best preformance ive ever seen.... and it works the same with any nerf micro :)
