Stainless steel would last you much longer than aluminum. Aluminum is not as dense as steel, and may not last as long.
Stainless steel is rust resistant; iron rusts easily. A stainless steel water gate will last longer than an iron one.
The life span of stainless steel depends on the type of stainless steel, the environment it is located, and the surface treatment. There is micro-pitting that will occur with out effecting the structural integrity of the steel but will tarnish the 'stainless' appearance. If the environment is free of heavy moisture and corrosive chemicals 316 stainless steel will last 1200 years with out significant decay.
Screws hold better, but stainless steel nails last longer. Why not use stainless steel screws? They're the best of both worlds.
There are steel horses over Vantage, Washington (Grandfather releases the ponies) that are expected to last 50,000 years. Stainless steel might last even longer, depending upon the grade. Stainless steel encased in a thick, airtight glass case should last practically forever. Stainless steel wire dragging behind a tractor trailer on a northern deiced coastal freeway, however, might only survive a few days.
Stainless steel exhausts are expensive but last a long time; they do not rust away like regular steel exhausts. Stainless steel exhausts are populat on custom, prestige and kit cars. A good staimless exhaust will last the lifetime of a car and never need replacing. It will, however discolour form the heat!

Stainless steel microwaves mostly are just for looks, but there are some advantages. The first one is that they last longer than traditional microwaves. The second advantage is that they are easier to keep clean. Then last of all is that stainless steel hides minor scratches and if the scratch can be seen, it can be buffed out.
To make it last for a long time
stainless steel, for the last 15 years or so
