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.

∙ 16y agopossibly because copper is more expensive.
some electrical prongs are just coated. Copper is too soft and the prongs would bend and become a hazard. Plus copper is more costly.

Brass is harder wearing, so will not alter its shape. However, the copper is the better electrical conductor.

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.
How do you take a cap off of a sewer clean out?
Depends if it is a cap or a plug or no hub or a brass /lead plug
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

What is the purpose of 5 Pins plug in wall industrial socket?
Different pin configurations define different configurations of voltage and amperage. Your receptacle could be a three phase four wire grounding receptacle. To see more go to related linksbelow.
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.

Why is metal used for the pins of an electric plug?
Probably because brass is generally tarnish resistant /doesn't discolour so easily Although brass is not as conductive as silver, copper, and aluminum it is less expensive to make and generally easier to work with.
