The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current
Metal with a lower melting point is preferred for fuse wire to reduce the risk of fire.
fhhjjf
Copper is used in the contact points in fuse boxes because it will oxidize and you can separate the points of contact. If it was made if iron and rusted, it will 'weld' the link together and then it is no longer a fuse.
If a thick copper wire is used in a fuse then by definition of a fuse this device would no longer be defined as a fuse. A fuse in a circuit is used to protect the conductors feeding the load of that circuit. The circuit, if using a thick copper wire in a fuse, would then be considered as a non fused circuit.
copper and tin
tin lead alloybasically tin lead allows are used . but other metals which have low melting point and appropriate resistivity can be used
Apparently mainly tinned copper is used in fuse wires. I have heard that there are a lot of other metals used as teh fuse wire though!

Because those metals have a high meling point, so it's easier and safer to use fuse wire which melts at a lower teamp.
yes very safe.add. Fuse wire is usually made of tin-plated copper. The fuse wire may well get warm in service, and a bare copper wire will gradually oxidize and will fail sooner as a consequence.
The common metals used in fuse elements are zinc, copper, silver, aluminum, or alloys. Bear in mind that, of them, copper has one of the highest melting points so is only used for specific high temperature fuses. For domestic use the alloy fuse is used.
