Alumen, a Latin word, derived in the English language from aluminum and
this, in the term that we use in the Spanish language: aluminum. The
concept is used to name the substance that has 13 as an atomic
This chemical element is a metal that is present in large
quantities on our planet. Its components are found in animals, plants and
stones, for example.
aluminum, whose symbol is Al, is used in many sectors of
the industry thanks to its properties. Its
toughness, malleability and ductility make it a highly appreciated material for
the manufacture of various types of products. Its appearance, which resembles silver,
also allows the creation of decorative elements or coatings.
Among the most appreciated properties of aluminum, its ability to conduct electric
current and its strength to resist wear stand out. On the other hand,
it is an economical material compared to other metals.
Aluminum can be found in countless products that we use in our daily
lives. There are tables and chairs that are made of this material,
as well as kitchen utensils, construction profiles, a type of paper, key chains,
hooks known as clips, and many other items.
Aluminum manages to be an appropriate material for such dissimilar products thanks
to the different treatments it receives and the various alloys it
is subjected to. In this sense, the most frequent aluminum alloys are made with
copper, silicon, magnesium and zinc.
It should be noted that aluminum is a recyclable material,
which can be recovered without experiencing changes in its properties. What is
done is to re-melt the aluminum or its scrap to obtain again a metal capable of
This material is among the most beneficial to those who
recycle it, since its characteristics make it especially profitable and it is
known that it will continue to be used for a long time before humanity can or
wants to replace it. Of course, economic interests are only one side of the
coin: the fact that aluminum gets along so well with recycling pleases those who
care about the environment, since its use reduces the abuse of natural
Aluminum has many properties that make it irresistible to more than one
industry; in addition to its aforementioned ability to preserve its qualities
once recycled, it stands out for:
* its great percentage of energy: it contains 15 kWh for
* its value as waste: this represents an important incentive
for the economy;
* its lightness: at the same volume, it weighs about a third
of steel and copper;
* its resistance to corrosion: which makes aluminum an ideal
material for the construction of products that are exposed to excessive or
little delicate use;
* its durability: related to the previous point;
* its ability to conduct heat and electricity: a complementary
aspect to its resistance, which considerably extends its field
* not be toxic or magnetic: what avoids certain problems and
restrictions of use in the products;
* effectively reflect light - this makes it ideal for interior
* be odorless and waterproof: it does not require many
precautions to maintain it.
All this explains why aluminum is so widely used in various sectors, such as electricity
and communication (where it has slowly replaced copper since the 1950s
for the manufacture of high-voltage transmission lines), transportation (its
presence in the automotive industry is growing), building and
construction (for door and window structures, as well as for covering
surfaces as large as a stadium).
