[QUOTE="birdiemc, post: 1792186, member: 29632"] Wonderman you got me interested. Looks like the folks manufacturing cartridge brass recommend avoiding acetic acid. Obviously the big thing I was missing is not all acids are created equally and the chemical composition of a particular acid reacts with cartridge brass in different ways. It seems acetic acid causes Dezincification in brass what I've found shows that it will leech the zinc out depositing copper onto the surface causing the copper to oxidize and turn green, like the statue of liberty. "70/30 brass should not be used with acetic acid..." [URL]https://www.azom.com/amp/article.aspx?ArticleID=4387[/URL] "C260 Cartridge brass is used in greater quantity than other copper-zinc alloys. It is the most ductile and has good to excellent corrosion resistance in many environments except where certain acids exist such as nitric, acetic, hydrochloric acid and ammonia/ammonia compounds. Easily machined and often clod formed. Typical Industry Applications: [LIST] [*]Mechanical fasteners such as pins, rivets, grommets, eyelets, screws [*]Decorative hardware [*]Electrical components such as connectors, flashlight shells, lamp fixtures [*]Ammunition shell casings" [/LIST] [URL]https://www.industrial-metals.com/c260-cartridge-brass[/URL] "C26000 Cartridge Brass is the most ductile of the brasses and is used in greater quantity than any other copper-zinc alloy.
