Zinc

Sierra 18-6013 is a zinc anode plate made for MerCruiser Alpha drives. It is listed as the Alpha One Pre-1990 anode and is intended for use on Alpha One SS units. The plate is made of zinc. Because it is tied to the Alpha One SS, match it to your drive before you replace an anode with it, and do not assume it fits other MerCruiser drive generations.

Our take

The Alpha One SS fitment is the detail that decides this anode: Sierra describes the 18-6013 as a Pre-1990 Alpha One plate in zinc. On a boat that means checking your drive generation first, since this plate is tied to those earlier units.
