Aluminum kettle wall thickness

phidelt844 · Nov 14, 2008

I've tried searching but haven't been able to find what I'm looking for. I am looking to pick up a 60 qt aluminum kettle, but am unsure whether it's worth an extra $30 for another 2mm of thickness. Here are the two I'm comparing:

4mm: Aluminum Stock Pot W/O Cover - 60 Qt., Stock Pots, Cookware

6mm: Aluminum Stock Pot w/o Cover 60 Qt., Stock Pots, Cookware

Any advice on an optimal thickness for large aluminum kettles? Will 4mm cut it, or is it worthwhile to just spring for the extra width?

I have an 80 quart pot that I use for crawfish boils and 2 30 quart pots that I use for brewing. All 3 are 4 mm. and after 6 years of use I have no complaints.

You might want to check these out. I have the 40qt. medium weight pot. It is 4 mm and it's thick enough I drilled and tapped it for 3/8ths pipe thread. Just screwed a nipple in it and then screwed on a valve. No weldless kit needed.

6mm??

I know you're not joking, but dang! That's almost 1/4" thick!!

It just seems slightly on the ridiculous side, but I use SS kettles, and 1.5mm is considered THICK - 6mm, Ohmygawd!

Aluminum is quite definitely easier to machine, though.

Unless you have a Sampsonite gorilla living in your brewing area, I would go with the 4mm thickness one. I have one of those cheapie 7.5 gallon AL turkey fryer and I managed to drop it from 3 ft half full of water onto the deck and it barely put a dent in it.

thicker it is the more even heat you will have.
