A. Hi Sachin. Things you might want to investigate include sodium benzotriazole ⇦ on eBay or Amazon [affil link] and variants, and chromate conversion coating. Good luck.

Q. Sir,
We are currently using benzotriazole but can you suggest any superior metal protection?
A. If I or a reader compose a second and third suggestion, Sachin, they may also be dismissed with "we already tried that" like my first 🙂
Can we therefore do it the opposite way with you telling us what you've tried? Thanks.

Q. I am an engineer in a company manufacturing copper and brass rolled products, addition of arsenic during melting stage gives a good resistance to Oxidation, but the setup requires a large investment. Can I get a solution to solve the oxidation once the rolled product is ready and the resistance to the same last for a longer duration. ⇦ Answer?
Sachin Pareek [returning]A. Hi Sachin. My second suggestion was chromate conversion coating.
Luck & Regards,
