Fuse wire is charaterized by high resistance and low melting point to avoid surge of ac current through it.
resistance means the te power to resist the heat or the electric current/ eg: tungsten which is used to make the filament of the bulb has a high melting point even when it burns on a high temperature so it has a high resistance, whereas in the wire of an electrical fuse has a low melting point as it burns at a high temperature...
low melting point and high conductivity
low melting point and high conductivity
From a plumbing point of view, i however have never heard of this being done. Lead pipes however are illegal and outlawed and they would never be fused together anyway.
The purpose of a cold heat soldering iron is to fuse electronic components, pipes and other metal materials together by melting solder as a connector which hardens as it cools. You can learn how a cold heat soldering iron works and it's different purpose at the HowStuffWorks website.
Low resistance and low melting point by "justquikr.com"
low resistivity and low melting point.
It has high specific resistance and low melting point.........
The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current

Yes they do
This is necessary because a fuse is a protection against an overcurrent; excessive current produce melting.
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...
No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.
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.
Spelter, sometimes known as zinc, is used to fuse metals with a higher melting point. The actual melting point of spelter is 787.15 degrees Fahrenheit.
There's a thin metal wire with a low melting point inside a fuse.It may be a nichrome wire.However copper wire is not suitable to be the thin wire inside a fuse cause it has a very high melting point.
