That is the reason why the transmission ...
Is silver a good conductor?
Silver has a higher conductivity compared to copper but isn’t utilized extensively because of its cost. But it does have some niche uses where extremely low resistance is wanted, some of them are; sensitive scientific instruments; cryogenics (where it’s desired to have minimal heat produced in wires); and also in electrical contacts in switches, where the softness of silver and relatively good-conducting silver-oxide makes it a good choice for metal-to-metal connections.

In certain situations, a network will use just one type of cable, but some networks will employ a variety of wire types. The variety of cable chosen for a network is directly associated with the network’s protocol and its size.
Does aluminum conduct better than copper?
Aluminum does not conduct well compared with copper – for a given size of cable copper will conduct better; but because aluminum has a better weight-to-conductivity ratio, aluminum cable with the same conductivity as the copper wire would be physically thicker, but would still work out to be lighter, and probably cheaper too.
Why do wire forming projects use a secondary material?
Many wire forming projects use a specialized coating of a secondary material to protect the actual wire form from exposure to harsh chemicals and high temperatures —helping prolong the useful life of the wire form.

Another austenitic stainless steel, Grade 316 SS is even more resistant to corrosion than 304 SS is. In particular, 316 stainless steel is better at resisting chlorides (like salt) and is often used in cookware and naval applications because of this fact.
Does metal have impurities?
Even if a piece of metal doesn’t have oxide on its surface, it probably still contains some impurities. It’s not uncommon for newly produced metal to contain inorganic compounds like trace metals.

Does pickling remove metal?
Depending on the application for which the metal is intended , these impurities may hinder its performance. Pickling, however, can remove most impurities thanks to the acidic properties of pickle liquor.
Does hot rolled steel have an oxide layer?
It’s not uncommon for newly produced metal to have a layer of impurities on the surface. Hot-rolled steel, for example, develops an oxide layer when worked. The presence of this oxide prevents the steel from obtaining a smooth and clean surface. Although there are numerous ways to remove oxide from steel, manufacturing companies often prefer pickling because of its simplicity. When pickled, the acidic pickle liquor eats away at the oxide layer without harming or otherwise disturbing the underlying steel.
