Why are boutique fuses made with gold or silver fuse wire? One possible issue with any fuse is that the internal wire does get quite hot in normal use and the resistance will vary with the current.
Gold and silver have very similar temperature coefficients to copper.
A far better choice would be nichrome or constantin.
Twenty years ago I was designing cards with wire ended fuses. These would avoid the two pressure contacts of a conventional fuse in holder
