As I have a choice of material from which to cut the parts, has anyone found any noticeable difference between say 5000 series alloy and 6082T6, which seems to be the standard offering

I have had one hull professionally welded, which cost £100, and I've had a go at fully brazing a hull myself, with Durafix sticks. The join was OK but the heat needed warped the floor, as it is half the thickness of the hull sides.
I'm thinking that it should be possible to tack weld the sides together, then slowly build up the number of attachment points, as the thermal conductivity of the aluminium should prevent adjacent joins from coming undone, especially if I use some steel as heat sinks. Doing it this way means that I only need to heat up around an inch of join at a time, so the thermal expansion should be minimised.
