The issue isn't so much with the materail choice (well maybe a bit...) but rather with the factory coating (annodize). Once the coating wears off, the magnesium/aluminum wears quickly and results in sharp edges on the gears that can wear the belt. I think steel would have similar deficits (oxidation, strength, weight, etc.)
The dry film lubricant provides a long-wearing surface and has been designed for this exact application. As long as you don't have deep grooves in your current gears, they should be able to be re-coated (at a fraction of what they cost new) and put back into service.
