om...

My boat (Crowther 50' cat) calls for 4mm 5083 plate, but I'm sure 5086
is fine, and I could probably go a bit thicker if I don't install the
dishwasher and the dive compressor. =^) Let's talk, tell me what you
need and we'll try to find a way to work together.


Please, please, talk to the designers before you start changing materials or
thickness. I don't have my reference books here at home but the two alloys
do have different properties.

One site I quickly checked gave following properties:
3-6mm plate:

5083-H116 UTS = 305 MPa, Y.S.= 210 MPa, 10% elongation
(the stuff I would normally specify)

5083-H112 UTS = 275 MPa, Y.S. = 125 MPa, 10% elongation
5086-H112 UTS = 250 MPa, Y.S. = 125 MPa, 8% elongation
