What Should Be Added or Changed?

Azure Electrum should get an alloy forge recipe like crimson steel & tyrian steel, as at the moment it is the only endgame metal without one.

Why Should This Be Done?

It would make crafting Azure Electrum easier & efficient, a suggestion for the forge recipe could be:
A block of azure silver
2 gold ingots
1 Ender Pearl
to create 3 Azure Electrum, to keep it in line with crimson steel.
