As far as certainly metals in ultrasonic the ONLY one I've come across that won't work is Magnesium. It'll pit the holy hell out of it for whatever reason. As for getting in to hard to reach places and get dirt out, it will do that too. If it's REALLY caked on though, you'll have to put it in for a while, rinse, and repeat until it's the desired cleanliness. Anything really burnt on may have to be blasted out.

Aluminum works just fine. Just pulled the breather cover from a 1975 CB550 out of the cleaner minutes ago. It sat outside for over 20 years and it got all of the crap off of it, plus all the old oil residue on the inside as well. They really are great machines for pretty much anything. They work great on rubber, plastic, some elctronics are ok to throw in. Really if you're running into a lot of dirty crap, get the biggest one that you can afford.

I'm actually thinking about upgrading...
