We ran a test shim; straight Hydrocloric acid removed .007 material in about 10 minutes very aggressive.

I am no chemist, what chemical do we use, be specific. Thanks

What do you mean by basic solution

We are trying to remove an aluminum shim .375 thick by 3” x 3” that is wedged between a 4340 metal Key block and a large roll mill. Question if we use sulfuric acid to eat the aluminum shim out, will it harm or erode the Steel encased on each side of the key.
