What applications have aluminum shafts? Ford & GM have vehicles with aluminum driveshafts (i.e. Aerostar, Corvette, GMC Truck, Firebird)
Why do the U-Joints have a protective coating? To stop galvanic action (corrosion) between aluminum & steel.
Where is the coating applied? The cups are steel, this requires a protective coating on the outer surface that makes contact with the yoke lugs & bearing bores.  Without a special coating between the surfaces of aluminum to steel, the aluminum pits, flakes & crumbles.
How is this done? A chemical process developed and used in order to stop galvanic corrosion has been applied.  A barrier coating between .0002" - .0005" thick is applied to the outer diameter of the cups.

Don't risk using standard universal joints without the chemical coating applied.  Protect your customers expensive aluminum driveshafts!
