I know that certified engine installations will use both.  Yes, its true that steel resists fatiuge better.  But that does not mean it is the only option, or even the best one.  I would think that in going from an aluminimum case to an aluminum flared tube, an alum. fitting would be optimal in most cases.

I have alum. fittings on my drive, and in most places in my plane.  Heck thats what comes in the kit.  :-)

The drain holes on the C drive are of course behind the tape.  The other two pics show the B, and C drives for comparison.
