Copper grease is generally the best thing to prevent seizing.


Copper grease is a bad choice for aluminium though.

Really? It's the standard choice for wheels.

I wouldn't use copper grease when in contact with aluminuim components.
I work in the offshore industry where a lot of aluminuim is used and we
use a different type of grease, apparently the copper accelerates the
corrosion of aluminuim when in contact with salt water. I'm not an
engineer or chemist, but have had it drilled into me for many years not
to do that, so I use the same principal when working on my car. No
copper grease near the Alloy wheels etc. I managed to source high temp
grease without copper to use on the pads etc when I had alloy calipers.
It seems to be as good as copper grease.
