Yes. Where conductors are used at radio frequencies, a 'skin effect' is thought to take place, and often the conductors are plated with silver, which has a higher conductivity than copper.
Another more common example is in electronic plugs and sockets, where the pins are often plated with gold, so as to minimize contact resistance. Gold is unreactive, and this gold plating offers little hold for corrosion that would otherwise interfere with the passage of electrical signals.
A third example would be in high voltage transmission lines, where a steel core is used for strength, and this is given a wrapping of aluminum sheathing. This is not true plating, but gives higher conductivity for a given span which would otherwise be limited by the breaking strain if aluminum alone. .

How do you use wires to heat something?
A: Nobody does that. Wires are good conductor never are to be used to heat anything, But there are special wire to do the heating
Can silver be used to make electrical wires?
Silver is used as a low resistance conductive material. Contactors and relays contact points are made of copper and are silver plated to obtain the lowest resistance between the moving contact faces.
How many wire or core in three phase electrical connection and single-phase electrical connection?
A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor. A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.
Megger value for single conductor?
It depends on the value of voltage being applied to the wire in normal use. Voltages up to 750 volts can be used on wires reading as low as .5 meg ohms. Engineers like to see 5 meg ohms on conductor readings.
When a section of electrified railway is isolated why are earth wires attached to the contact and return conductor wire?
When a section of the electrified railway is isolated, the earth wires are attached to the contact as they help it in grounding.
What is a substance that is a poor conductor of electricity and is used to coat wires?
A conductor and a switch
Can a coat hanger be used as a distributor wire?
A coat hanger is a horrible conductor of electric current. Doubt if it would work. Also most distributor wires are hot. Since coat hangers aren't coated it could easily ground out.
What is a poor conductor of electricity and is used to coat wires?
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
What is copper used for as an electrical conductor?
Wires.
Is copper an insulator or a conductor?
It is a very good conductor. It is used in wiring to deliver electricity.
Is copper conductor or insulators?
Conductor, which is why it's used for wires.
Why are copper wires used instead of steel wires?
I think copper is cheaper.
Why is steel not used for electric wires?
Because steel is not a good conductor of electricity. Copper is the best conductor for electricity.
Why is copper used for telephone wires?
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
Where do you connect blue and brown wires in European and UK wiring?
These colour wires are used in European and UK wiring. The blue wire is used to the identify the neutral conductor and the brown wire is used to identify the "hot" conductor.In Canada and the US. The white wire is used to the identify the neutral conductor and the any colour but green is used to identify the "hot" conductor.
Is polythene a thermal conductor?
No, polythene is a plastic and that cannot conduct electricity.
Is a coat a conductor?
a coat is an insulator because it keeps heat in
