Contacts could be spring brass or beryllium copper, fuse material is
whatever the element is,  often stamped zinc I think.  Which is
highly active electrolytically.  Yes, I didn't mention that but it's
the major reason a Euro fuse will corrode sitting right next to an
AGC or SFE fuse that's fine.  Unfortunately the ATO fuses are a step
backwards in that regard, as their spade terminals are simply
extensions of the element and can present the same problems.  They
do, however, have a lot more contact area.
