I have yet to encounter any mechanism in Vex that absolutely needs aluminum gears or chain. I've barely ever snapped the plastic chain, and only once have I stripped a tooth off a gear. (And that was because the limit switch used to protect the arm mechanism had been become unplugged).

Especially with Vex robots, if the mechanism you have keeps snapping chain, or it keeps stripping gears, you should probably reconsider the basic design of the mechanism, instead of just going with the "get a bigger hammer" route.

On a less than 10 pound robot powered by a [fingernail-sized] motor, if you need aluminum gears, something is wrong.
