Bitcoin Backup Markers

Metals have different characteristics. Tungsten is the metal that has the highest melting point which is far higher than steel and titanium, but it is brittle at room temperature, especially when it is under stress. Titanium has higher melting point than steel, also 40 to 45% lighter than steel, but it is expensive than steel. They are both good for seed phrase backup. But for a marker that can resist temperature up to 1000°C no need to waste money on titanium because steel melting point is higher than that. Also steel is good if you want to go for engraving.

Sounds like the steel would be the most reasonable option, imo.

Especially for those who are looking for something that wouldn't hit the rails due to the price.. After all, I do think we would need to get not one copy for engraving what we need.

I saw these online to know how strong good markers are: https://youtu.be/HbRTSfCtvWI?si=XN4E_TydJxgZ_2Pf

I checked out the video, and I think the ability of the maker to withstand heat at higher temperatures is not so bad. However, I've some concerns. I noticed the word written on the steel plate that was subjected to heat was much bigger, and it took most portion of the steel plate. If you want to write the seedphrase on "that particular steel plate", you'd have to write the letters smaller so that all the seeds can fit in. Hence, to know how effective the maker can be, a 12 or 24-word seed phrase should be written on the plate. If after heating, the seeds still come out well, then the marker can be a good alternative to an engraving pen.

I think these marker are regular size marker and you can also use them as usual to write on small steel or ceramic depending on your size of writing.

Regular size marker has big strokes, and you can't write small fonts/letters on it to fit on a regular size backup steel, although manageable for some with little hand writing i guess, but idk. That's why a smaller engraver with quality steel might be probably doable.

These markers are great because of survival in very high heat much hotter than typical house fire and they are also waterproof so words can not get messed up. And knowledge which you shared is helpful and it is good to keep in mind that different colors have different heat limits and people should check before buying.

In my point of view to make this information even better you could also look that how long ink lasts in sunlight and maybe compare this method to other options like stamping or engraving. All in all this is  really good guide for anyone who wants strong physical backup of their Seed phrase information.

Even when applying text with these markers on a titanium plate, 1 vulnerability inherent in any paint remains (this is the principle by which these markers "work") - this is vulnerability to scratches (this has already been voiced above).

Yes, but you can also scratch over stainless steel engraved letters and destroy backup, it's not a big deal if you know how to do it.
If they are using this paint markers in aviation than I am sure scratches are not affecting them easily.
I would also say that it's much harder to engrave letters to the metal, you need special tools and hammer, especially for small plates.

These markers are indeed great as another form of backup, but the "technical data sheet" of Dykem confuses me... It basically says it's flammable, so it requires a lot of care ^{[e.g., because of static discharges, everything should be grounded, avoid direct sunlight and a few other things]} and for a marker that can withstand very high temperatures, I find it to be weird!

I think it needs some time to dry in air, and than it becomes fire-proof.
Edding 751 and 750 are probably available everywhere in the world, and it's much easier to purchase them locally.
This is another advantage, you don't need to order anything online and wait delivery from different countries to create your durable backup.
