AntiSieze Lubricants
Aluminum is the cheapest, for most general use.
Nickel is the most-expensive, for high-temperature use like oxygen sensors & exhaust fasteners.
NONE OF THESE is an electrical grease, or a dielectric grease, or a lubricant for moving parts. They only lubricate tight fasteners so they can be loosened after long periods of being static &/or hot. They do NOT prevent corrosion or wear; they only reduce galvanic action & galling.
