Which Metals Were Used?

[AdvenJack]

Friends,

Were the engine cases, cylinders, pistons, rings, crank shafts, connecting rods, etc.,
all the parts of the engines in the WWI era and prior, made of steel exclusively? Or
were a variety of metals used for this part or that? I love to here details as you know
them. Thank you as always.
