Huh? There's no graphite in WD-40. 

It's just a non-volatile oil in a volatile solution;  the volatile stuff lets it seep in and displace water ("WD" stands for "water displacement"), then evaporates (which is what "volatile" means), leaving the oil behind. You won't find any graphite left behind, that's for sure. WD-40 isn't even a particularly good lubricant; it is an effective solvent, though, and it also conveys the oil into places that ordinarily couldn't be reached, either because they're too tight or because there's water in them.

WD40 is essentially compounded from finely-ground graphite,
suspended (in theory, anyway) in a light petroleum-based
compound...! One can buy various petroleum-based compounds
intended for (and sold as) freeing rusted-together nuts vs. bolts...!
