What I do to God Mode items into server is: cheat gfi PrimalItemResource_Metal_Cobalt 1 0 0 <---- this will give you 1 Cobalt.
To find all the other names of items, just go to your Atlas install directory: \steamapps\common\ATLAS\ShooterGame\Content\Atlas\AtlasCoreBP\Items The item names are all in The "Items" Directory just browse yourself and you can GodMode to your hearts content.
