steel tube and aluminium
A welded steel-tube frame carries the loads, with aluminium (and some fibreglass) skins over it. An open welded steel-tube frame with a plexiglass bubble. This is how the Bell 47 family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
