Dwiin is Steel if that helps

Piggy-bagging off of Kul do Dovah, we are only given dwiin (steel) and yuvon (gold) for metals. If you have specific metals, just transliterate them into Dovahzul. For example: IRON, SILVER (or ARGENTIUM, the Latin equivalent), TITANIUM, ORIKHALKUM (Orichalcum), etc. Alternatively, you can describe them. For example, silver could be described as viintaas sot dwiin, although admittedly that's weak and might not do it justice.
