I've recently finished the Mistborn trilogy by Brandon Sanderson and at the very end of the book:

Sazed tells Spook: "P.S. There are still two metals that nobody knows about. You might want to poke about and see if you can figure out what they are. I think they'll interest you."

Is there a reliable answer to what they are and what they do? If there is another book to read that answers this please let me know.

    Someone really needs to fix the front pages so that spoilerized text doesn't show. – Xantec Sep 13 '11 at 2:14

    I'm guessing you have already visited this site . The link provided there does not work. – Darius Sep 13 '11 at 3:02
  • @Xantec:Check out the "Alloy of Law" preview chapters on tor.com, where one of the characters can use one of the two remaining metals. It's a new trilogy set in the mistborn universe and releasing really soon. – apoorv020 Sep 13 '11 at 11:27
  • Brandon has said he is going to write an Alloy of Law sequel, which may turn into a trilogy. – Corwin01 Aug 21 '12 at 17:09

The two unknown metals are Cadmium and Bendalloy, which allow the burner to slow down or speed up the flow of time in a bubble that surrounds them.


Sanderson answered this question on his forum. While it is now offline, you can still find it in Arcanum.

3) The last two metals are Chromium and Nicrosil. We'll reveal what they do on the Allomancy poster. Suffice it to say that in the next trilogy, the main protagonist would be a Nicrosil Misting. And, to make a Robert Jordan-type comment, what those two metals do should become obvious to the serious student of Allomancy... (It has to do with the nature of the metal groupings.)


With the lead from @Darius and some additional digging I managed to find this table of Allomantic metals, which can apparently be bought through Brandon Sanderson's website (although I can't get the store to load).

    You should typically try to include the relevant text from hyperlinks into your answer, it makes them much much better. – apoorv020 Sep 13 '11 at 16:46

    Second link is now dead, I can't find a suitable replacement to what you might be referring. – kingledion Nov 25 '18 at 20:09

A list of all the metals I can find goes like this, there are 19,

Iron, steel, tin, pewter, zinc, brass, copper, bronze, aluminum, deralumin, gold, electrum, atium, and the eleventh metal: malatium. The new metals would be chromium, nicrosil, bednalloy, cadmium, and lerasium.
