ok i talked to a buddy today that is way into materials. not just the generic metal head, but is freakishly into. anyway i started asking questions bla bla bla brass, al, cu etc..... what will happen if i do a,b,c,d..... so i start talking about a resivoir i am thinking about trying out but the problem is that i have to use al and there will be copper in the system and what in gods name should i do. Sorry this might get long. anyway the first thing he asked was is there going to be liquid in the system and when i said yeah, well he didn't like it but said there are solutions. anyway he then started in on all sorts of numbers and i said...whooooo back the truck up. Anyway he started spitting numbers that were a little more generic. basically there are 7 generic groups of al
1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx, 7xxx. he spouted some stuff that i just ignored or maybe i was boored then it got a little interesting. 1xxx, 2xxx, 3xxx are all very corrosive, he said dont use 4xxx al i forget why(i think because it had a cu mix to it but that confused me even more), but 5xxx and 6xxx al had some very interesting properties. They are both very corrosive resistant al. I asked about cu and brass on those al and he pretty much said that they would handle it fine. so the question i have for you guys now is what types of al are you using and what are your observations? oh yeah 7xxx al is aircraft grade al :P
