Aluminum Pulleys - Durability??

Aluminum Pulleys - Durability??

Aluminum Pulleys - Durability??

(OP)
Does anybody have any experience with Aluminum Pulleys?  I am trying to replace some existing steel pulleys with aluminum ones.  They are used on a military  vehicle where reduced weight is critical.  They drive a large alternator and requires a 12 rib K-Section automotive style belt drive.  I am leaning towards a 6061-T6 Aluminum with a hardcoat anodizing.  My biggest fear is the wear rate compared to the steel pulleys.  I wouldn't have a problem with having them replaced due to wear every 5 years but not once a year - if you know what I mean.  Cost is not as big a factor as weight.  Any comments or suggestions, good articlas or web pages???

RE: Aluminum Pulleys - Durability??

You will find that a stamped steel pulley will weight probably less than an equivalent Al pulley and outlast the Al one by several times factor, try to find a standard replacement part from a vehicle manufacturer that will do the job and forget the Al option, we have used Al pulleys for several years and they are a good solution if wear is not a factor. By weight I will go the steel route.

Cheers
