because brass is generally tarnish resisant so it does not discolours easily and also because brass is not such expensive as copper

<<>>

The pins are make of brass because it is a harder metal than copper and will wear better through use over its lifetime.

What materials - exact materials - and manufacturing processes are used in making a 3 pin plug?

The typical household plug is made from pins: brass reason: cheap, wear and corrosion resistant and a good conductor (not compared to gold/silver/plat/copper) process: forging/casting (not sure) housing: ABS or PVC reason: cheap, easy to colour, corrosion resistant, easy to clean, hard wearing made process: injection molding.

What are examples of loop-back plug?

A loop-back plug is a device used to test network equipment by sending signals back to the source. Common examples include a serial loop-back plug, which connects the transmit and receive pins on a serial port, and an Ethernet loop-back plug, which connects specific pins on an RJ45 connector to test network interfaces. These plugs are essential for diagnosing and troubleshooting connectivity issues in networking devices.


How copper is annealed?

Its done with a fame or torch, you heat the copper to a almost cherry red glow, (caution, you don't want it red, if it just starts to glow, "stop" that where you just annealed copper. but the more you shape it after your annealing process it will harden up again, not due to cooling but due to your shaping it

Why are the three pin plugs are made of brass and not copper or steel?

Brass is used for the manufacture of plug pins for the following reasons. It is a good electrical conductor and is cheaper than other materials such as copper. It is a hard alloy material, therefore it is very wear resistant and will not wear or mark easily. Furthermore, Brass is corosion resistant and will not tarnish easily. Brass is also stiff and therefore will not bend easily when inserted in to the socket.


What are the pins for a 13 amp plug made from?

The pins of a 13 amp plug are typically made from brass, which is chosen for its excellent conductivity and resistance to corrosion. They are often plated with nickel to provide additional protection against wear and oxidation. The design ensures a secure and reliable electrical connection while also adhering to safety standards.

What does the inside of a plug look like?

There are three wires-the live wire, which is red or brown, the neutral wire, which is blue, and the earthing wire, which is yellow or green. The live wire has high voltage, and supplies electricity. The earthing wire brings the electricity safely to the ground in case of an electrical fault. There is also a fuse, which in case of a huge surge of power would melt, breaking the circuit and preventing an accident.
