I came across this the other day looking for parts online. I've always seen them made from billet or stainless steel. I know JHM uses an aluminium pulley. This is substantially less in price than the other pulleys. Thoughts? Not trying to go cheap, just looking for some feedback from someone using an aluminium pulley.
I deal with them from time to time on different applications and I've had some with 80,000hrs on them and no real signs of wear (machine at work).
