I believe everything you mentioned, with the exception of the crankcase, are steel. The case is aluminum alloy.

The crankcase, piston, and the exterior of the cylinder "barrel" (also known as a jug or block) are made of aluminum alloy. There is a liner made of steel that is pressed into the cylinder "barrel", that the piston rings contact.

As mentioned previously, the crankshaft, piston connecting rods, piston rings and piston wrist pins are made of steel too.
