permatex anti-seize

Hey,
So i have been using Permatex Aluminum anti-seize for changing my spark plugs.
I never noticed there is Cooper and Nickel... what is the difference?

so I stay wuth Aluminum even thou they are meant for Marine? thx

 

Looks like the difference may be temperature ratings with aluminum being lowest (1600 F), then copper (1800 F), then nickel (2400 F).

I realize that's Loctite, not Permatex but Permatex uses the same temperature ratings for each type and I couldn't find them with temp ratings all on one page.

I imagine either the copper or nickel will be about the same for a truck. It just depends on which color you want smeared all over everything and anything you're handling while using it.

 

The copper anti-seize is for high heat applications. Probably “better” for spark plugs but I generally use dielectric grease for my spark plugs and never had a problem. I don’t know what the temp rating is for it, but I’d imagine that the copper antiseize is higher.

 

yeah I saw the temp difference... I dont think my tacoma would go that high, but the copper and nickel temp is a lot better than Aluminum.

 

You use dielectric grease on the threads?

 

FYI: Permatex is owned by Loctite. The actual compounds weather Permatex or Loctite are probably the same.

 

I had kind of gathered that from all of their products that I have used but wasn't certain.

 

I’ve used both copper and aluminum anti seize on my spark plugs. I can detect no difference.

 

I do. Never had an issue.

 

ok I ordered more of the aluminum anti-seize.. thank you

 

I have always known dielectric grease for thigs such as spark plug boots.

 

It’s good for preventing corrosion on electrical connectors and light bulbs but since it’s a grease it can also prevent galling or seizing on the threads of the plugs.

 

I have always used No 2 pencil lead. No problems. Haven't had to change the plugs on the Tacoma, tho.

 

I use the Copper based on things going into Aluminum.

The Aluminum based for the hardware going into steel

 

Temperate range is just one difference. Another MAJOR difference is compatibility between then the base metals and environmental conditions. For instance, the aluminum is usually "finer" and is better suited for very closely fitting parts or fine screw threads. Copper anti-seize may not be a good idea in environments where copper corrosion is going to be an issue (generally not used in marine environments for instance). Zinc is often used when joining aluminum to aluminum, like in the airline industry. I don't know why, but it seems most of the "food grade" ones are aluminum based.
