Another suggestion, can we change tungsten to adamantine?
Basically it has nearly the same properties as tungsten (albeit literally diamond-hard) but in our world it's called Adamantine. Otherwise it's roughly as rare as real life tungsten and perhaps we'll see them in composite shells in later war cannon munitions.
There'd be another material called Adamantium which is a type of adamantine alloy created by dwarves. It's dense and hard but also has some more elasticity thus it's more enduring overall.
Dwarves guard the secret to the proper creation of this alloy and technically each clan has their own variation on Adamantium (with various minor differences).

What do you think?

Meh. I think that I'm the only one that explicitly has a lot of dwarves (They are probably something like 15-25% of the population) and I was considering something similar as a unique material, but decided that like in the last RP my nation won't have any unique materials.

Last game Tin was already a superpower because of its absurd size, and this game the Commonwealth is both big and diverse. Its comparatively huge dwarven and gnomish population are like a unique resource, since they have made the place lead the way in terms of technological development for heavy industry, ground vehicles, and to a lesser extent chemicals.

And yeah, to refute the inevitable counterpoint that this wouldn't be a "unique material" to just me, nobody else seems to have that many dwarves. And also, since this is a rare and expensive metal, I'd assume that the Commonwealth with its habit of building gigantic vehicles and war machines (and tons of dwarves to work the adamantine) would be using the metal far more than anybody else.
