==== Vitreous metal ====
[[Amorphous metal]] is a variety of alloys (e.g. [[Metglas]]) that are non-crystalline or glassy. These are being used to create high-efficiency transformers.  The materials can be highly responsive to magnetic fields for low hysteresis losses, and they can also have lower conductivity to reduce eddy current losses. Power utilities are currently making widespread use of these transformers for new installations.<ref>{{cite web |title=Metglas® Amorphous Metal Materials – Distribution Transformers |url=https://www.hitachimetals.com/infrastructure-energy/clean-energy-technology/metglas-amorphous-metal-materials-distribution-transformers.php |access-date=25 September 2020}}</ref> High mechanical strength and corrosion resistance are also common properties of metallic glasses which are positive for this application.<ref>{{Cite journal|last1=Inoue|first1=A.|last2=Kong|first2=F.
