i'm changing out my stator at the moment, and I would like to say up front, whoever invented these stupid black paper gaskets - i hope you have fun in hell.
that said.
I was looking around my garage for materials that i could scrape with that wouldn't mar up the aluminum stator cover. i found some bronze, some copper. But looking online, all of these are harder than aluminum.
Then I started scrolling back through the Mohs hardness scale chart, and it caught my eye. Aluminum is 2.75 on the Mohs scale, but just under that at 2.5 is Silver.
I guess not everyone collects silver, but back when it was cheap, I did. I have "several" rounds of .999 fine silver, enough to sacrifice one for science. and sure enough it doesn't leave a mark on my engine cover. So I took the ugliest one ounce piece i have, one that i already used in an electrolysis experiment, and beat on it with a hammer until one side was a bit sharp. it's not perfect but it's actually working pretty well. I can bear down on it as hard as i like and the aluminum is still perfect. it makes me wish i had a square shaped ounce bar. that would be ideal. but the round coin works alright.
maybe it would be more reasonable if silver was still 15 bucks an ounce or whatever. Right now it's still close to 70. But beating on this silver round with a hammer doesn't make it weigh any less B)
magnesium and zinc are also about the same hardness as silver, but i don't exactly have a chunk of either just lying around ... B)
