Safe storage of Crypto Seed words is very risky in recent times as they are to be kept safe from different types of online and offline attacks. There are different types of threats such as online hackers, hardware failures, fire, water, rust and corrosion etc. depending upon the types of seed storage devices you have selected.
There are different types of online and offline storage devices such as;
- Online/ Hot Storage Devices – Mobile Wallets, Exchange Wallets, Desktop Wallets
- Offline/ Cold Storage Devices – Paper wallet, Hardware wallet, Metal Wallet
Out of these, the most popular one is Metal Wallets. Its durability and resistance to fire, water, rust and corrosion make it popular as a safe device for storing crypto seed words. Another attraction of metal wallets is that it can also be used as a secondary storage device.
What are the different types of Metals used for storing the crypto seed words?
Then the next question will be about the types of metals used for storing the crypto seed words. We can mainly use the five types of metals and the selection of the metal depends upon the individual choice of each customer.
Here you have the following options for entering the seed words into the metal plates:
a) Enter Full Seedwords directly in metal plate
b) Enter the first 4 letters of the Seedwords directly in the metal plate
c) Enter the numbers associated with these keywords instead of directly recording the same. Here you can code the keywords on the basis of the BIP39 list.
In all these cases, you can use a Scribing Pen, Alphabet &/ Number Punches, or Electric Engraver for entering details on the metal plate.

Types of Metals used for storing crypto seed words:
1.Titanium:
It provides a simple yet powerful backup that can withstand fire, flooding, and other harsh environments. It supports any 12 or 24-word seed and is perfect for storing your private Crypto seed words. Titanium Melting temperature is 1668 C/3030 (F).
2.Stainless Steel:
Digital Wallet details can be stored into stainless steel plates for a simple yet powerful backup. It can store your Private Crypto seed safely and it supports any 12 or 24 word seed. Stainless Steel Melting Temperature is 1510 (C )/ 2750 (F).
3.Copper:
You can backup your Nano Ledger, Trezor or Keepkey seed phrases into Copper plate as they can withstand any harsh environment.It also supports any 12 or 24-word seed and is perfect for storing your private Crypto seed for a long time. Copper Melting Temperature is 1084 (C) / 1990 (F).
4.Brass:
It supports any 12 or 24-word seed and it can be kept as a powerful backup as it helps to restore the Crypto currency wallet from the information stored into these plates. Brass Melting Temperature is 930 (C )/ 1700 (F).
5.Aluminium:
Aluminium plates can also withstand fire, flooding, and other harsh environments and they also support 12-24 word seeds. The melting point of Titanium Wallets is 660 (C )/ 1218 (F).
Points to be keep in mind while using Metal Plates:
- Even Though the metal plates are uncrushable, they may bend if not used with a hard surface at the time of punching. So it is always advised to use the same with Jewellers block.
- They should be properly cleaned before starting engraving/ stamping as the dust or any other substances should be removed from the plate for a better output.
- Always practice punching on another plate before starting the actual punching.
- You can increase the safety of the seed words by splitting them into one or more metal plates and can even hand them over to your friends or families as a secondary backup.
Conclusion:
All these metal plates are fireproof, corrosion-resistant, acid-resistant and virtually uncrushable and are a better seed storage alternative than paper/ hardware wallets. You can select the best one keeping in mind the durability, resistance to corrosion/acid and also by considering the price with its quality.
