I admit that this is an extreme example, but for the sake of $100, you could store your Bitcoin backup seed words onto something specially designed to be corrosion-resistant.

This is why Domino plates are made from 316L (marine-grade) stainless steel.

But why not titanium?

Titanium has a similar strength to stainless steel, at almost half the weight (an advantage for aircraft); however, titanium is more brittle. Furthermore, a UC Berkeley study found that titanium becomes even more brittle with just a few extra atoms of oxygen... “[it] is like poison to titanium" ...not a good quality for long-lasting, robust storage plates: https://news.berkeley.edu/2015/02/05/oxygen-titanium/


316L stainless steel performs better than titanium at extreme changes in temperature (ie. cold water sprayed onto a house fire), and is also why Elon Musk chose stainless steel for the SpaceX rockets: https://www.labroots.com/trending/space/17708/why-spacex-using-heavy-stainless-steel-starship
