Case, cylinder head, piston, and piston pin.

Is anything else made of aluminum in a typical Continental or Lycoming engine?
 
Wrist pins are not Al

Accessery case is, as is oil sump

I think the wrist pin is steel and at least some pistons have some steel in them but the majority of that is aluminium. All of the case including the accessory case plus on some engines the rocker covers and the sump is aluminium. Cylinders, camshaft, gears and crank are all steel. The oil transfer collar and oil pickup tube are probably aluminum and at least part of the oil cooler. There's aluminum in most of the accessories including alternator, vacuum pump, and magnetos plus intake runners, throttle body or carburetor.

0-300 has a mag oil sump, and accessory case and the 0-200 has a steel sump.

Carburetor, pushrod tubes, magneto housings, alternator case, starter housing, alternator pulley, The thingy the starter ring gear bolts to, intercylinder baffles, oil cooler, some but not all oil pump housings, etc...
 
The Rotax 912 series uses AU for pistons and cylinders. The clyinders are ceramic coated and the tolerances are .001 between the piston and cylinder. This is, why they are water cooled heads, to keep the expansion rate of the metal more precisely the same. It is rare to use any oil between changes. They are an amazing aircraft engine.

That's an expensive material to use in an engine...
 
Crank case
Accessory case
Oil sump (some)
Pistons
Piston pin caps (some)

If you want to get picky you can start naming off fittings, random covers for unused accessory pads blah blah blah

Thank you, all.

One reason I asked was to learn where Aluminum particles can come from, if they are found in oil.

Gold? That is just a trifle. You should see the platinum engine!

Oh wait, that's from Continental. Never mind.

I was wondering how long it would take for someone to notice.
