Copper antiseize compound vs. silver
Stumbled onto info in another thread that it may be bad idea to use a copper based anti-seize compound for spark plugs in an *aluminum* head, and should use one of the silver colored compounds instead? How come? I thought copper was a better conductor for enhancing the ground connection from head-to-plug?

Re: Copper antiseize compound vs. silver (Lone Ranger)
Maybe its because some metals just don't go good together. With the right combination of metals you actually create a battery like situation, where one is cathodic to the other. I know if you put two metals side by side in a solution you can make battery, depending on how dissimular the metals are...Damn that is how batterys are actually made :lol: But seriously if you have the right combination of metals together one will draw current from the other and the one that the current leaves deteriorates.
Not sure if that is the reason but could be. BTW Copper anti seize is for higher temperatures than the silver. Much higher than your engine should be. :smash:

:cheers: Use the Silver! (aluminum)
Copper and aluminum don't get along! Aluminum will breakdown in the presence of copper and moisture (electrolysis)
May take a long time for it to happen, but play it safe

Whoa, that was close. I just bought my NGKs today and going to try and put them in tomorrow. The anti-seize I bought said for aluminum heads, but it's copper based. Think I'll go trade it tomorrow for silver.

Got one can left of the original Anti-Seize. You know, the one you can't buy any more with the carcinogenic carrier and nickel. Great stuff. A little tiny bit goes a long way.

Re: Copper antiseize compound vs. silver (h rocks)
The silver is actually nickel based, not aluminum based.
We have experienced SERIOUS corrosion problems in offshore and deepwater oilfield applications when using copper based anti-sieze with stainless steel fasteners. We don't use aluminum (corrodes WAY too quickly) so I can't speak to the compatibility there, but if you are using stainless steel fasteners, like ARP stuff that I use, I would strongly recommend using silver anti-sieze. You may not have the catastrophic failures we've seen, but it can't be good in any conditions to have the copper stuff on stainless.

Our nuke grade AS is nickel based, and what makes it nuke grade is that the carrier is certified as low chloride/low halide, less than 250ppm total halides.
That just means that it doesn't facilitate chloride-aggravated stress cracking in stainless steels at high temps and pressures.
