This looks like stainless steel on the outside, but the rougher surface inside has to be aluminum!! Any proof from manufacturer that this

Hello Hazelnut, good evening. I would hazard a guess that it is probably stainless because the pot was probably contoured using a mold where the sheet of stainless was placed and a ram pushed it creating the pot. Making it out of 2 metals would be far more laborious and therefore costly and why my guess is that its all stainless.

According to the manufacturer's spec sheet, it is all stainless steel, in and out, including the filter basket and perk tube.

A magnetic test will not prove that there isn't aluminum in there. As a matter of fact, some stainless steel will even hold a magnet! It all depend on the grade of SS. I will be testing for aluminum and this pot may be going back! I did NOT want ALU or PET at ALL!!!! Or at least NOT where any of my water or coffee will be sitting!!

I am not sure but it cleans up like a dream and makes wonderful coffee. the outside is still shiney and wipes clean and looks new. I wash the in side peices in the dish washer and they look aluminum but do not discolor. I would buy this coffee pot again .

Aluminum is not magnetic. I successfully stuck a magnet to the inside and out so it cant be aluminum.

I had another perc that was stovetop and the inside was shinier. I can't really say what the inside is. I do love this pot. It has never let me down and tastes like the old stovetop one.

No proof, but it looks like brushed stainless to me. Aluminum changes after washing over time - the coffee pot inside has not changed.

I own this percolator and LOVE it ! It is stainless inside and out. Hope this helps. :)

I just called Presto. It is all stainless steel, except for the small "cup" at the bottom that the perk tube fits into - that is aluminum. I asked if it was lined with anything and they didn't know.

No. It is a brushed finish. I think aluminum or brushed steel. It does look like it is stainless steel.

There is a thin strip of stainless around the outside. It does work very well, but that's all the stainless there is.

It looks like a light weight stainless steel or a sturdy gauge stainless aluminum. Not quite sure and I just tossed the box & literature.

I would think it should be stainless,but as far as I know, it is not. Well, you gave me an idea though for my next purchase :)

This is not nonstick aluminum, all stainless as far as I know. It was a gift for someone.

It's aluminum. If it were iron or steel it would weigh a ton! It is cast aluminum, meaning the aluminum is melted and poured into a mold. This makes the edges rough and gives it a cast iron look.

The lining of the base heating unit looks to be aluminum. The "crock" food container is shinier and could be stainless steel is quite lightweight so I can not be sure if it's stainless steel or polished aluminum.

I would guess stainless. Definitely not plastic, and too heavy for aluminum.

I explicitly asked Zenith if it was made entirely of stainless steel, inside and out. They told me it is made of stainless steel, not a stainless steel coating. Judging by the other answers below, looks like no one's got any rust to speak of. Mine came with a major scrape on it, so the dark grey rougher metal is exposed. I will see if any rust appears in a few months.

The "foil" is a very specially hardened stainless steel. Aluminum would be far too soft to function as a cutting edge! There's an incredible amount of thinking that goes into that very special material.

It is not stainless and it is most likely aluminium but coated with a non-stick surface.

Mine is stainless on outside. Inside has to be wiped out after use or i suppose it would rust eventually. Mine isn't rusting.

It's not stainless steel. It's either aluminum or aluminum alloy. I can't tell the difference. Hope this help.

its metal- doesn't look like stainless to me- more like aluminum with some kind of protective coating on it in my opinion

I'm not certain but I know it's not aluminum, not the one we bought and it's some form of cast iron but it's been awhile since we bought it, you should ask the seller, they should know that answer best.

I don't know. It doesn't say on the bottom. So, I will assume that it is not stainless steel. Sorry, I couldn't help more.
