I have disassembled Neozed fuses and they had the flat conductor with holes punched in it down to 16 amps. All embedded into some kind of sand that helps extinguish the arc.
I think the older Diazed dont have the holes. You can sometimes see the end of fuse conductor at the side of the metal end caps.

Btw, Siemens give a thermal loss of 1,7 Watts for a 32A neozed operating at full current.
