I believe that the track record of aluminum pulleys is not good. There is a report of one falling apart and grenading under the hood and others with loose rivets after some use.
Aluminum is easy to machine and that is about its only useful value here.
Code 3 and others made aluminum pulleys and then went to steel pulleys I think.
