Personally, if it was me, I would look to do it in 3-4mm 5251.

5251 has good corrosion properties.

+ 1 for 5251.

Used it at work on some more robust aircraft panels, should work a treat for a floor pan! Its more like a mid-strength Ally and like Brett says its got good corrosion properties.

Thanks Rob,

what other things can i do to stop the corrosion, between alloy, and steel?? ive been told a good bonding agent will help, and also useing a earth strap will help............ any comments please

HI,

I meant to say....... A Good Bonding Agent

Like those above, I also used 5251. 3mm would be fine.

Mick,
Also, don't forget to use sealed rivets, don't use blind rivets.

Im still in the planning/fund raising/getting permission from the misses stage but im planning on using either JC11 Celloseal or Duralac jointing compound. Both will protect against dissimilar metal corrosion and should give you some protection from water getting in through the floor pan aswell. You could also use PRC 1750 but its mainly used for fillet seals and weather seals.

hi,
thanks to everyone for their help....

Brett Im not really knowledgable on rivets...would it be best to use stainless steel rivets ??

Mick,
Its the type of rivet. See the picture, blind rivets can leak.

Here is a link to show more examples: http://www.npfasteners.com/sealed-rivets.shtml

Could you also give a source for the rivets?

Could you also give a source for the rivets?

in the US they are known as closed end rivets. try Rivets - Fasteners - Rivet Gun - POP Rivets - Hanson Rivet.com

I got lucky and found a 4x12 sheet of 7075-T7 .083" at Boeing surplus. You can put very slight bends in it. That an equivalent of .160" in 6061-T6.
