The most you’ll get to is high copper content alloys for fuse holder electrical contacts and fuse support/retention. Pure copper materials for electrical contact design and build, are generally an eliminated product or material. Too soft to be safe over the long term in safety/approval, etc.
This, specifically for the high power inlet and fusing aspects of electrical equipment. Basically anything that has to deal with variance/stability in tension/retention or has pressures that have to be maintained. Like spring clips for a fuse. Pure Copper is too dangerous/soft in the long term (Across thousands of individual items--it’s a failure rate thing), so it’s brass or things like tellurium copper/or and beryllium copper.
this is easily found via looking at the specs for fuse holders in a search at lets say - digikey. it’s one of the standard parameters supplied. Additionally, they will usually supply information on the coating or plating type. Same for fuses themselves.
Thus one can look for fuse holders that spec beryllium copper alloys with silver plating. And thus avoid brass and tin plating and the like as a contact material in fuses or fuse holders...
