Indeed. In fact, pretty much any well-engineered item will use a collection of different parts. Once you get into moving mechanisms especially it is useful to use complimentary materials to reduce friction, prevent wear and tear, etc.
A car is made from an astonishingly selection of materials to form a functioning whole, a smartphone is the same. Hell, a cap from a plastic coke bottle normally has two different kinds of plastic in it. One for the cap itself, and one for the small insert that helps seal it. Hard plastic for the cap, soft for the seal.
I just found that one in particular amusing as an engineer. It has more holes than substance.
