Electrum?

Which mod adds electrum? I have an additional suggestion for its use and I want to make sure I'm posting on the correct forum for whichever mod adds it

 

I believe it is Thermal Expansion.

 

Thermal Expansion and GregTech both add Electrum; it's a more mainstream item in Thermal Expansion (largely for liquid redstone power items) whereas it's a convenience item in GregTech (bonuses to circuit production if you use it instead of redstone).

 

kk, thanks for the info <3
