zinc, copper, silver, aluminum, alloys or metals that have low melting point
The material suitable for making a fuse wire should have a low melting pt. so that it can easily melt and cut off the flow of current and save the electrical appliance...
A 40-amp fuse is typically recommended for 8-gauge wire. It's important to follow the manufacturer's recommendations for fuse sizes based on the specific application and electrical load. Using the correct fuse size helps protect the wire from overheating and potential damage.
By 'fuse', I assume that you are referring to the fuse element (fuse wire), rather than the complete fuse?A fuse element is an alloy, such as tin and lead. Alloys such as these exhibit what is called 'eutectic' action. This means that the alloy retains the good conductivity (e.g. of the tin), but has a lower melting point (e.g. thanks to the lead).
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.

The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor. As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.

NO. Usually the positive wire will have the fuse.
The wire may not melt and break if an unsafe current is produced.
Fuse wire is designed to open under over current conditions. Just like a fuse.
The 15 amp fuse.
A circuit breaker does not have a wire fuse in it.
