So I am planning to do some maintenance for EXUP valves on the motorcycle and many links are suggesting to use copper grease.

I have some Permatex silver anti seize laying around. Can I use it?

Thanks for the help.

The copper grease seems to hold up to heat better, but I would use what you got unless you can wait for Amazon to bring you some C5-A.

Thanks, yeah one I have can go up to 1600 and C5-A is 1800 degrees.

Any idea if I can C5-A or similar locally at Walmart or AAP or even pep Boys?

Thanks

Sure! You should be able to find the Permatex version of copper antiseize locally. It is also good up to 1800 F. Check NAPA if no one else has it.

Copper and Aluminum are on opposite sides of the electro-negativity chart. One acts like a battery anode, and the other acts like a battery cathode. Put them together and you get major corrosion. Not a good idea.

Copper based anti-seize grease used on steel or iron is probably a good idea, but I would not use it on anything with Aluminum.

In basic Chemistry the teacher told a story about someone who used brass pipe fittings on the cooling connections on a very expensive Aluminum mold. After about a year the corrosion at the brass (brass has copper in it) and Aluminum connections was soooooo bad that the entire mold had to be scrapped.

Also, nail up copper gutters with Aluminum roofing nails and in a year or so the gutters will fall down.

Do not use copper based anti-seize on an Aluminum head.

That's where I am planning to use : https://www.tapatalk.com/groups/fazer1000/exup-valve-maintenance-t1524.html

What should I use? Silver Permatex or Copper anti seize?

Those parts should be steel, so it should not matter as much.

BTW, Aluminum melts at 1220.58 degrees Fahrenheit, so if your motorcycle has Aluminum heads why would you be worried about using an anti-seize that is ONLY good up to 1600 F.

Honestly, I have no clue. In the link I posted above it say to use copper and I only have silver one.

Hence I asked the question, so I should be good to go with silver Permatex anti seize and lubricant, right?

What has always been brought up at this point is that Permatex actually states on their web site about copper antiseize: "Suggested Applications: Spark plug threads installed in aluminum". Go figure. It leaves anyone knowledgeable about galvanic corrosion scratching their head.

Do not drop a penny in the bilges of your aluminium sailboat either.

“Galvanic corrosion does not occur when dissimilar metals are completely dry,”.....water needs to be present for galvanic corrosion to occur.

not in this application. Water is not hanging around these areas typically.
