Mike,
LOL - I have quotes coming from 2 mills (Alaskan and HM Hillman), but don't have them yet! I'm expecting both back by tomorrow, and am a little concerned about $, yes. [ponder] I know there will be a heavy premium for the thicker plate at least (it looks I can get the 4 inch and 8 inch...
Thanks, EdStainless. 70/30 is the way I was leaning - I'm replacing 6061-T6 with Cu-Ni in my underwater housing design and the somewhat higher strength of 70/30 versus 90/10 is attractive in order to minimise any wall thickness design changes.
That brings up one other question if anyone can...
Great link - copper.org has a wealth of info on their site. I'll let you know how it all turns out. Thanks again - you've been helpful to this poster noob. [thumbsup2]

Thanks a bunch, Mike. Rolling a sheet and welding on the flanges is probably my best bet. Going with thinner plate certainly opens up the availability of materials. I'll probably oversise the plate so I have some to machine off. I don't suspect post-roll stress relieving is overly necessary...
Thanks for the quick reply!
Just to help clarify, the cylindrical part of the housing is essentially in the form of a hoop/annular ring, with some reinforcement. The end caps are essentially large flat plates, with some weight saving mill-outs. I also use an internal custom chassis to...
Howdy,
I need to migrate the design of a large underwater instrument housing from Al 6061-T6 (hard anodised, with sacrifical anodes) to a near-maintenance-free material for permanent underwater installation in a harbour environment. I would appreicate any suggestions for this replacement...
