Copper is a metal having high melting point and very low specific resistance. in case of excess current flowing in the circuit it will not be able to melt wire quickly and break the circuit protecting it.
You can't use it because it has the same melting point as the pipe you are trying to seal. It just will not work. What you use has to have a lower melting point than what you are trying to weld or attach to.
It is not pure enough
copper wire
Copper. The wire is made of elemntal copper not a chemical compound. (Note the copper used may sometimes be alloyed with another metal or occasionally be a solid solution of small amounts of oxide in the pure metal. This improves the durability and handling characteristics of the wire.)

No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
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.
The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current
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!
copper and tin
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.
