The most durable electrical materials and supplies

Metals are naturally occurring materials which are perfect for support electric recitations, or inside minerals from which they are extracted, and each of them has different characteristics. Based on these, each mineral lends itself to a different use. This is why it is important to know them well.

The most durable electrical materials and supplies

Aluminium, for example, is a very light and resistant material and is used relatively recently because a large amount of electricity is needed to extract it from the minerals that contain it. It is used to manufacture containers for food and beverages (the classic aluminium trays, or the cans of cola and orangeade), to cover the frames, but also in the aeronautics industry, and with it the parts of the engines that are to be read are made.

Metals like copper and tin have been used for thousands of years because they have a relatively low melting temperature and our ancestors could easily use them. These are also very ductile materials and are suitable for the production of alloys: copper, for example, can be joined to tin to obtain bronze, as well as zinc to obtain brass. With copper, you can make pots, but it is also used in electric wires as it conducts very well, instead the tin, which does not oxidize easily and resists corrosion, is mainly used as a coating (for example inside the cans used for keep food).

Silver is the best conductor of heat and electricity among all metals, but is also used to make coins, in photography and in jewellery. Still on precious metals, gold, a soft, ductile and very malleable metal, is used in dentistry, in the electronics industry and obviously also in jewellery, through electrical wholesalers Chester services and across the UK.

Iron is very strong and resistant, and its alloy, steel, but the strongest and most “strongest” metal is titanium, whose alloys are used in the aeronautical and aerospace industry.

How do they work?

They are excellent conductors of both current and heat and possess a crystalline structure. During the formation of the crystal the necessary energy is supplied to release valence electrons, one or two per atom. All the other electrons remain anchored to their respective nuclei, to form a total of ions, which oscillate around their equilibrium position with increasing amplitude as the temperature increases.

The model developed for the metallic conductors is called “free electrons“. This model hypothesizes, in fact, valence electrons no longer linked to a single atom but shared in an electronic cloud. The motion of free electrons can be:

  • Disordered, similar to the thermal agitation of gases, when the conductor is not subjected to an electric field
  • Ordered in direction and towards, overlapping the disordered motion, when the conductor is subjected to the dynamic action of an electric force field. Thus, passage of electric current from one end of the conductor to the other.
