The water heater is aluminum and the plug is plastic for a reason.
dissimilar metals can gall into place over time.
Aluminum water heaters do not need anode protection.
The anode was designed for steel water heaters to prevent corrosion.
I have used my Plastic plug for 7 years now with no problems. It is pipe thread and can be replaced at any hardware store.
If this advice does not ring true and you decide to used a brass or steel threaded plug or anode then at least use nickel anti-sieze or teflon tape on the threads.
Best choice... Keep the plastic!
