Metal compatability for hinges?

Johnny said:

you have done an AWESOME job on your build so far !!

not to give you a yes or no to your question:
but, many of us use stainless fasteners with aluminum parts
with little to no ill effects. If you are in a total salt water environment,
you may see more incompatability than someone in the middle states.
how often your boat gets wet and stays wet during storage is another factor.
a paper mill in your neighborhood will definately be another negative factor.

I ran across this article on the subject by Fastenal Fasteners the other day.
you might find it an interesting read for any future concerns.

paper mills produce tons of sulfuric acid rain in a 1 mile radius.
especially bad on mornings with heavy fog.
you can not fully understand the damage a paper mill can do unless
you have lived near one. The upper management at a paper mill have covered
parking areas..... general employees park outside in the open and this is a
photo of a typical "mill car".

At the exit of the mill, there is a spray wash that you drive through to "help"
wash off the junk that the mill creates.
items such as window air conditioners and car radiators with aluminum cooling fins
really suffer a short life span. Boats in the area with aluminum anything also
exhibits faster than normal corrossion.
