Oddly enough, there aren't many different kinds of materials used to build this camera. Most of the parts are made out of steel or aluminum.
It's sometimes hard to tell though, because most of the parts are painted black, to make sure the inside of the camera is as dark as possible. By checking the magnetism of each part, it's easy to distinguish steel from aluminum.

Many parts are made out of aluminum because of the small weight of the material and its easy to machine and process. That's why the body of the camera is made out of this material.
But parts that need to rotate or move and can't afford to break or deform, it's best to use steel. Steel weighs more than aluminum but its toughness makes it more resistent to deformation.
Parts like small gear wheels and screws are made out of brass. Brass is an alloy of copper and zinc. It's also not magnetic and has a typical yellow-brownish color.
Special parts like the lenses, the viewfinder, hand grip, lens cap and so on are made out of certain kinds of plastic.
