What metal is used in electric fuse?

Fuses have tinned copper wire* in them.The normal current-carrying capacity of a fuse is determined by the thickness of the wire, as is the final rupture current.Because fuses "melt" like solder, some people think they must contain solder wire, but that is not true.Solder has a lower temperature melting point than either lead or tin but it is not used in fuses because it does not have as good a normal current-carrying capacity as tinned copper.* "Tinned copper wire" means the copper wire has been dipped in a bath of molten tin during its manufacture, leaving a thin coating of tin on the surface of the copper. (The tin is used to help protect the copper from corroding in the atmosphere.)


Is the silver speaker wire copper?

Yes; it is tinned copper.


What is tinned copper wire?

Tinned copper wire is copper wire that has been coated with a thin layer of tin. This coating helps to prevent oxidation and corrosion, making the wire more durable and long-lasting. It is commonly used in electrical applications and soldering.


What is the difference between a tinned wire and overcoat wire?

Overcoat: Individual strands of tin copper stranded together & then covered with a tin coating. Topcoat: Bare (untinned) copper wire, stranded, then coated with pure tin.


How do you solder copper to brass fittings?

Take either an SOS pad or a wire brush and rough up both the inside of the brass fitting and outside of copper pipe, put the copper pipe into the fitting and solder around it.


Why do you need to tin first the wire before soldering it?

pre tinning make it easier to solder wire because the solder is already " stuck" to the wire. and less solder will be needed to join the wire. if you watch the solder under a magnifier while tinning, you will notice the solder does not flow and "stick" until proper heat and flux ar applied. this heat usually is more than required to melt the solder because it takes mor heat to heat up the wire due to higher density. after tinning, less heat is required to melt the solder, and enough flux is usually left from tinning to quickly join the wire to the desired material provided the material is also tinned. this reduces cold solder and provides for a more relible connection. To tin the wire first is to cover the end of the wire with a layer of solder before you put it thru the hole in the PCB that will give you insurance of a proper electrical contact else you will put a heap of solder on the PCB without a proper contact with the wire itself what is called a dry joint that go for un tinted copper wire only normally all electronic component pins is factory tinted


Can you connect copper wires to tin coated copper wires?

Yes, you can connect copper wires to tin coated copper wires using a soldering iron and solder. The tin coating can be heated and merged with the copper wire to create a strong electrical connection. Heat the wires together and apply solder until it melts and flows over the connection point, forming a bond.


Can a insulated ground wire be used in lieu of a tinned bare ground wire?

No, an insulated ground wire cannot be used in place of a tinned bare ground wire. The grounding wire must have a bare tinned copper conductor to provide a proper and effective path for excess electrical currents to flow safely to ground. Using an insulated wire can create safety hazards and may not meet electrical code requirements.


How can a copper wire b silver on the outside?

Its probably not silver. Its probably tin plated to make it easier to solder.


How can I effectively solder copper pipes?

To effectively solder copper pipes, follow these steps: Clean the pipes and fittings thoroughly with emery cloth or a wire brush. Apply flux to the cleaned surfaces to help the solder adhere. Heat the joint evenly with a propane torch until it is hot enough to melt the solder. Apply the solder to the joint, allowing it to flow into the connection. Let the joint cool and wipe away any excess solder.


Why is copper used in electricty?

Copper is a very good conductor of electricity that is easy to form into wire.


What is the difference between stranded copper and tinseld copper wire?

bare copper is pure copper, while tinned copper is having light coating of Tin over it, preferred where soldering phenomenon is req. while the bare copper is good conductor then tinned copper.
