    Carbon steerer require carbon stem?

    Building up a frame very slowly.

    Any thoughts on whether a carbon fork such as the Easton EC90 SLX requires a carbon stem -- carbon against carbon -- or is alu ok?

    My instinct is that I don't like the idea of hard metal (edge?) against carbon at such a critical point.

    Anyone out there have actual experience of carbon steerer with an alu stem?

    It will be fine with Aluminum, just follow the correct torque specs and you wont have a problem.

    Alloy Al stems are great with carbon steerers. The only limitation with an all-carbon steerer vs a carbon fork with metal steerer is the spacer stack height must be limited to roughly the steerer diameter and not greater (lesser is OK, of course), that and you must use a steerer plug and not a star-nut.

    The maximum spacer stack is normally given as 25 mm (~1") for a 1" carbon steerer but Easton allows 50 mm (~2") for their 1-1/8" steerers.

    And, I concur, an Al stem is perfectly fine with a carbon steerer. In fact, that's how my newest bike is set-up.

    Stay within torque specs for the steerer as well as the stem. Trust me on this.

    I'll answer with a question:
    Does a carbon seatpost need a carbon frame?

    No. Go to any LBS and you will see plenty of carbon seatposts on AL frames. It's a marketing thing

    It's fine. Some fork manufacturers (I know Reynolds does) will warn against use of stems with an angled slot.
