Some reasons to use brass for plug pins

1
Why Should Electrical Plug Pins Be Made Of Brass?

• Edison discovered bulbs to get brightness at the
  ancient time, and as technology developed, many
  electrical appliances were discovered, so to
  resist overheating these appliances, plug pins
  were made. To include safety measures,
  manufacturers discovered three-pin electrical
  plug pins. Brass electrical plug pins were
  discovered to offer low resistance and more
  safety. 
• We regularly use appliances and plugins and plug
  them out often, so the pins become loose, and it
  increases the chance of electrical shock. So, to
  avoid this shock, brass is used to manufacture
  electrical plug pins.

Two-Pin And Three-Pin Electrical Plug Pins

• Before knowing why plug pins are made of brass,
  you must know the difference between a two-pin
  electrical plug pin and a three-pin electrical
  plug pin.
• Electrical plug pins are as crucial as electrical
  devices or electrical appliances. Because when
  you don't insert electrical plugs into the
  socket, all these electrical appliances won't
  work. 
• Electrical Plug pins are two types - 2 pins,
  electrical plug pins, and three electrical plug
  pins. Two pins are small in 3 pin electrical plug
  pins, but one pin is larger than the other two
  pins, which is called an Earth pin.

Do You Know Why It Is Significant?

• Generally, there are two pins in an electrical
  plug pin, one is live, and the other pin is
  neutral. The live pin is used to transmit the
  voltage from the power socket to the electrical
  appliances. 
• The neutral pin is used to keep the electrical
  appliances in a closed circuit only then will
  the current flow to the electrical appliances.
  The third pin is an earth pin, and there is a
  chance of electric build or electric leakage.
  During this electric build or electric leakage,
  there is a possibility of electric shock. To
  avoid this electric shock, an Earth pin is used.

Do You Know Why This Earth Pin Is Fat And Long?

• While we plug in, the earth pin comes in contact
  before neutral and the live pin in the socket.
  Due to this connection, the earth pin will
  discharge the static charge from the electrical
  appliances before the voltage is passed to the
  appliance. 
• Even while removing the plug, the earth pin will
  become contactless from the socket only after the
  live pin, and neutral pin are removed. This is
  because the earth pin will remove the static
  charge even when removing the plug from the
  socket.
• When the conductor is large and prominent, its
  resistance which means the property to resist the
  current flow will decrease, and at the same time,
  the ability to conduct current will increase. So,
  it will be helpful to discharge the static
  electricity efficiently.

• If the earth pin were small, there would have
  been confusion in the live pin, neutral pin, and
  earth pin. This confusion would have led to the
  insertion of a live pin, neutral pin, and earth
  pin at different places, leading to current
  shock. 
• There is a difference in earth pin, live pin, and
  neutral pin to avoid this confusion. 3 pin
  electrical plug pins are primarily used for metal
  appliances like refrigerators, washing machines,
  mixers, water heaters, etc. Because these metal
  appliances produce lots of static charges and
  discharge this static charge earth pin.
• Let's see whether it is worth it or not to get
  the plug pins with the brass.

Reasons To Use Brass For Plug Pins

• 1. Friction Cost
• Brass has a low-resistant property. Because of
  this low resistivity, it is used in plug pins. It
  is also inexpensive when compared to other
  metals.
• 2. High endurance
• It also has high strength. So that it might not
  become loose often while using it for
  appliances. 
• 3. Consistency
• Since brass is flexible and pliable, it makes
  work more accessible, and it is used widely.

• 4. Finalizing
• Manufacturers find it easy to give a complete
  finish to the brass materials. It is not hard to
  mold, so brass is used in making electrical plug
  pins.
• 5. Size
• The brass pins range up to 2 - 7 grams
  approximately. If all the terminals or plug
  points are brass, they will add up to a bit of
  weight.
• 6. Safety measure
• It is considered that brass pins are safer when
  compared to other pins. It safeguards appliances
  from damage.
• Two plug pins can sometimes produce shock due to
  lose wiring and short circuit, and avoid this
  type of issue with a three-pin brass electrical
  plug pin. The three-pin has an earth pin that
  helps to ground the current.

Features Of Brass

• Copper and brass are similar but have different
  properties.  
• Brass is a mixture of copper, zinc, Aluminium,
  and silicone. 
• It is used in making utensils, electric plugs,
  sockets, plumbing, and musical instruments. 
• It is corrosion-resistant but not saltwater. 
• It is a brightly golden-colored metal. Brass
  metal is widely used in decoration.

Prerequisites For A Brass Electric Plug Pin

• The prerequisites for a brass electric plug
  pin will specify the properties of the material.
  Let us see their properties.
• Overheating If the pins get hot, the risk of
  spark increases. The heating comes from the
  electricity brought out by the appliance and the
  resistance of the conductor. Therefore, brass has
  low electrical resistance in the pin.
• Firm fit The plug will be put in and discarded
  throughout its life. If the electric plug is used
  too much, the plug will be loose in the socket.
  The wear resistance of a material depends on its
  strength, so we use brass for high material
  strength.
• Low cost A brass electrical plug pin is low in
  cost, so we need to keep the material and
  processing costs down. However, the processing
  expenses will rely on to some extent.
• Thus, the brass electrical pin is a good
  conductor and also protects the appliances from
  shock.

Conclusion

• Brass is used in manufacturing electrical plug
  pins because of its vast excellent properties,
  and it is also cheaper when compared to other
  metals. Hence, brass is used as electrical plug
  pins for offering better safety.
