I have never heard of copper clad aluminum being used for network cable
(Cat5/6). Tinned copper, yes. Copper-clad steel wire used as fake copper wire,
yes. Undersized copper wire used in cheap/knock-off cable, yes (should be 22 or
24ga, some cheaper cable is 26ga, knock-off is sometimes 28 or even 30ga). No
direct experience, but it seems to me aluminum wire that small would be pretty
fragile and subject to fracture under bending.
