there should be many better metals in yggdrassil

in vol3 narberal said to momonga:

"But Ainz-sama, I don't believe a soft metal like Adamantium suits you. Maybe Soul-Emeralds, Gold-Rubies or one of the other Rainbow-Metals would be more suitable. These plebeians can't appreciate greatness."

being mentioned rainbow metal i guess there are at least 7 or more color metal

i think of some red-metal like the one shaltear armor is made of maybe something like scarletite

or black metal like albedo's armor
