my guess is that these are basic cables made of galvanized steel strands. i.e. not stainless, and not designed to be low drag.
Aero levers appear to be intended to be used with low drag cables, teflon lined housings, etc. It would probably still function, but not have the feel that you prefer.
I'd recommend trying a cable of this type before investing in a box of 100.
