Which materials are used to make the wings and the fuselage of an airliner, for example the Boeing 767 or the Airbus A320?

2$\begingroup$ this risks being a tad broad, all possible steel/aluminium/titanium alloys + fiber composites are quite a lot. But I concede that only a finite list is used for the fuselage/wings. Let's see what the answers bring, but if you could think of a way to narrow it down a bit, I think it might help. $\endgroup$ – Federico♦ Mar 29 '16 at 17:17

Most modern planes are made mostly of aircraft aluminum. Or at least are skinned in aluminum. The spars and cross members may be made of other materials but I am under the impression they are mainly aluminum as well. Generally high stress areas like wing/fuselage joints may be made of more rigid materials like steel. Aircraft Spruce provides a nice break down of the various types of aluminum here. This answer to a similar question provides a nice break down.
As the technology gets better and the facilities grow in both scale and ability, composites like carbon fiber have found their place in planes like the 787. Here is a break down for the 787
