I'm determined to do something unique for a countertop and don't want to spend the money on stainless steel and I want something sort of "industrial" looking.
Maybe I'm wrong but it seems to me that 1/4" thick (or thicker) sheet aluminum has some possibilities for a countertop.
I'd like a brushed, sealed finish and other than getting the pieces sheared, do the top myself.
I have a metal fabricator who I'm sure can laser cut the sink etc.
I suspect that you will find that aluminum will scratch pretty easy. The first time you try to slide something heavy you may end up with some deep gouges. I have stainless countertops in my shop and it would take a near constant effort to keep them looking good-if I was so inclined. Have you consided cement? I've seen some nice cement kitchen counter tops.
5052 is fairly corrosion resistant so it would probably "ok" for a work counter top. Brushed and sealed? Maybe clear anodized. 1/4" would be way overkill. .100 if supported under the main surface would be more than adequate. If you have the front edge rolled and the back bent up and back for a backsplash it would almsot be self supporting depending on length.
I think I would pass if you meant for a kitchen countertop. If just brushed aluminum then it it would constantly get scratched, and I am not really sure if hard anodized would be a lot better. I have a mini mill with a hard anodized table and it holds up ok, but it does scratch and a cutter goes through it like butter.
I like stainless for counter tops. Its harder to work with, but will last longer than you will live.
On one Army base the kitchen sink counter was galvanized steel. The zinc had long since worn away, but Army coffee removed the rust that formed during cleanup. If I quickly wiped it dry it stayed shiny until the next meal.
Temporarily cover your existing counter with a sheet of aluminum and see how it wears. I have a stainless plate on the counter for hot pots. The finish has become random fine scratches.

I'll second the notion of cementious countertops. There is more than one book devoted to the topic and the array of possibilities is not piffling.
If you consider the metal tile or plate idea elsewhere suggested in the thread, spend your money on Spectralock epoxy grout. Price comparison with the regular stuff will make you cringe. The durable result will make you prudently satisfied.
I read about the spectralock grout -- if I tile definetly will use it. If I use stainless steel tiles (source?) can I install edge to edge without grout?
Also, someone mentioned HARD anodize.
What about that?
I guess there must be a durability difference in anodize coatings?
I may just play with a 2 x 4 sheet of 1/8" 5052 -- brush it (and take it to the anodizer as well).
Hard Ano is so hard you can't scratch it with a carbide end mill and isn't electrically conductive. It's also pretty cheap to have a professional do it.

One of the reasons for grout with various ceramic and stone tiles is to prevent their cracking.
If you use SS tiles and can get a surgical edge interfit that prevents gunk from gathering in the interstices or erosive solutions from puddling or attacking the adhesive substrate, you are a free man. And don't forget that it is "stain less" not "stain proof". My broad concern would be whether you can satisfy those conditions, with one more to mention.
Should you predict having to replace a tile for any reason, the grout line also gives you a place to attack without easily damaging abutting tiles. Design structure separate, grout does have some functional justification.
If you use Spectralock, mix what you think you'll need instead of the containerized units. If you have any mixed stuff surplused, you can store it in a cold refrigerator for some time and use it later after a warm up renews the polymerization process.

Similar to regular anodizing, but thicker, and will have a brown or greenish color. It can be dyed darker colors. It's the new thing in cookware. You can have a look at wal-mart and see it on frying pans. As others have said it's brittle. If it flexes too much it will crack.

Reply: Costco had an aluminum patio table this week in the local store. Maybe look at that and see how the top handles some Costco pots.
