I am working on a project, all details can be found http://www.overclockers.com/forums/showthread.php?t=680115" is the catalog page with the options. I've googled about annealed and "dead soft" however I still can't tell exactly how soft/flexible it is. All I need it to support is water running. I also know the aluminum isn't the best for bending but I've read that at such thin pieces I should be able to get one bend out of it. Also perhaps there is a better metal to use in this case? I'd like to keep it cheap, but if there is something else around the price of the aluminum then its good.
