Mortar and (presumably) wall plugs for things to screw into on a machine tool? The epoxy would isolate the steel from the alloy, no corrosion issues. Mortar etches alloy on contact, and chances are it will end up on an external face no matter how careful you are, as well as shedding aggregate through any mounting holes.
