What is the difference; Tin & Aluminum? (And other Questions!)
I am not a metallurgist. That is likely painfully obvious by my thread title. I have a removable bow and aft casting deck project that I will get going in the spring. I am a cheap bugger and I am looking for cheap to free sources for my building material.
The decks will be aluminum as I want it to be super light weight and strong and I want it to last.
My bright ideas are as follows;
Aluminum framing/skeleton -
Will be made out of a couple of crushed/damaged aluminum ladders; Is this a good idea? Are these generally safe to use and strong enough (of course NOT using the damaged parts!).
Decking - Here is where it gets REAL muddy for me... I was thinking about using old aluminum siding... if I can find some. What I can easily get is corrugated tin roofing from the farm. This old roofing has never rusted and it has been outside for years. Could this mean that it is actually aluminum and NOT tin? I don't know the difference by looking at it. I think that tin visibly rusts and aluminum not as perceptible...
If the consensus is that this is not appropriate material to use, what would be suggested? (Think free scrap or REAL cheap!)
I will be fastening this all together with pop rivets and, perhaps self tapping screws. I will finish off the decks with exterior carpeting glued down with contact cement.

keep in mind just because you are building it out of aluminum doesnt mean it will be lighter. something overbuilt in aluminum will weigh the same as if it was made of wood.

Road signs, stop signs and most highway signs are anodized aluminum. Go to a scrap yard and hunt around for old signs. The men working signs used to be 4 x 4 aluminum and have since been replaced by poly signs. Go to a highway maintenance garage and scrounge. Aluminum ladder sides will work great for structure.
If you mix aluminum with other metals (Tin, steel etc.) you will cause corrosion due to premature Galvanic corrosion.
