I have heard that alumminum is not a good idea to boil in because it puts aluminum into your beer...but is it ok to use as a HLT? I am making my brew system and don't want to buy a brand new pot if i don't have to
It's fine for either.
Matter'o fact, there's a sticky in this very section about aluminum https://www.homebrewtalk.com/f11/faq-aluminum-pots-boil-kettles-49449/
I have heard that alumminum is not a good idea to boil in because it puts aluminum into your beer...
Which vendor or purchaser of a stainless kettle told you that gigantic lie?
Myths About Aluminum Pots:
- Aluminum pots will cause Alzheimer's disease. FALSE. This myth was debunked years ago by the medical research community, and the US National Institutes of Health and Health Canada have long since ruled out a connection between Alzheimer’s disease and aluminum cookware. If you don’t believe me, see the following:

- Boiling your wort in an aluminum pot will cause off-flavours in your beer. FALSE. Simply boiling a batch of wort will not remove enough metal from your aluminum pot to get into your beer and cause metallic off flavours, particularly if you build up a passive oxide layer inside the pot first. For new pots, this is easily achieved by either boiling the pot full of water for 30 mins to one hour, or by putting it in your oven for 10 mins at 350 F.
- Aluminum pots have very thin walls, and are not suitable for a boil kettle, particularly if you want to install a ball valve. FALSE. Thin- and thick-walled pots are made from both aluminum and stainless steel. The material they are made from is much less relevant that the thickness of the pot.
- Aluminum pots will react with very acidic materials, and wort is acidic. NOT REALLY. Wort isn’t acidic enough to cause a problem with an aluminum pot. In fact, both SS and aluminum are quite resistant to acidic materials, and you need to be concerned more about highly alkaline (i.e. basic or high pH) materials with your pots.
- Aluminum pots are simply not as durable as SS pots, so why bother, plus they will scratch easily and harbor bacteria. PERHAPS, BUT... Both aluminum and SS are durable enough for homebrewing if you are willing to invest just a small amount of care for your equipment. You simply aren’t going to wear out an aluminum pot in your brewing lifetime, so this is a moot argument. Furthermore, scratches aren’t really a concern with a kettle since the heat of the boil is going to sanitize it anyways.
The Bottom Line:
You can’t go wrong with a quality stainless steel pot, and they are a tried-and-true solution for lots of homebrewers. Yet, aluminum is a viable alternative that is much less expensive than SS. In fact, you can generally purchase a larger and heavier aluminum pot compared to the equivalently priced SS pot. In homebrewing, I guarantee you will really appreciate having a larger pot that is heavy and conducts heat well, speeding our boiling and cooling times and reducing scorching. In my mind, this far outweighs the cosmetic appeal and somewhat higher durability of a SS pot.
No one thaught to look at the faq. or do a search to see what info's here?
Yep, some have. But why should that stop someone from supplying personal opinion or opinion not associated with previous posted opinion? Though I am certain many who have been here for some time could be a bit put off by questions being raised over and over and over and over and over again.

Strong acid != CausticEdit: Did not want to be mis-construed, so replaced wording "Strong acid" with "caustic" for accuracy.
Strong acid != Caustic
It's exactly the opposite. Caustic solutions are very basic.
You mean, "corrosive."
Because when you are talking about something like this, no one want's 'opinions'. They want facts, not urban legends, and what someone might have heard once upon a time.Yep, some have.
