Essentially a fuse is a wire which has a low melting point because in case large current flows through the wire at a particular time the heat produced is proportional to the square of the current hence the fuse melts and the circuit is broken . Thus the appliance/gadget in use is saved from damage.
Whereas if we use copper wire with higher melting point it withstands higher temperature and the circuit is not broken immediately and hence the appliance gets affected by the large current.
So using Cu wire as fuse is dangerous.

If the current in a circuit becomes too high due to an electrical fault, fuse wire will melt and the circuit will be broken.
Copper wire will not melt and the circuit will be left carrying a high current which may lead to overheating and an outbreak of fire.

Because if you get a short in the system, you burn the house (or whatever) down. A fuse is there to open the circuit if too much current if flowing across it. Essentially it melts at a lower temperature than copper. By the time copper melts, anything flamable around it would have long since caught fire,.

Lemme first clarify what a Fuse precisely is. Fuse that is a skinny twine that may bear resistance of in common words certain magnitude. If the resistance someway will improve, (this means that warmth vacationing via that twine also will improve) then the fuse twine melts away combating your digital products from any damage. A copper twine can face up to countless resistance, so if u replace the fuse twine with a copper twine,then the present via that is going to also improve and your position equipment isn't in a position to face up to a lot cutting-edge..

Fuse has a rated blow out rate.. copper dosent usually
(penny behind the fuse syndrome Eh?)

bcoz copper has a low melting point.in case of short circuit the wire melts quickly.
