Uses of Copper
Copper is part of the world around
us. It is in our homes and offices, in our transportation
means, in sophisticated as well as artisanal artifacts, in
computers and industry, in small decorative objects and in
huge monuments.
Also, copper wires and cables transport energy and information.
Its presence may go unnoticed, but it is there, used as a
material that is resistant, durable, recyclable and with high
electrical and thermal conductivity. These properties ensure
its value as an essential raw material in the building of
our civilization that started thousands of years ago.
The refined copper commercialized by Codelco is later transformed
into raw material that supplies the industry that manufactures
the products that society consumes.
The construction industry is one of the main consumers of
copper, which is used in the wiring of buildings, in gas and
water tubings, heating systems, roos, finishings, or as a
structural component. A modern house requires some 200 Kg
of copper, almost two fold what was required 40 years ago,
since it has more bathrooms, electrical appliances, greater
comfort, phones and computers.
Copper is key for the generation and distribution of electricity,
since it is an excellent conductor of that type of energy.
In telecommunications, it is the prime raw material in the
manufacture of phone wires. In data transmission technologies,
the new developments also position copper as an excellent
option for broad band connectivity.
Among consumer articles, copper is very important in all
those related to electricity. A computer may have more than
2 Kg of copper, starting with the tiny microprocessors that
make it work, which more advanced models have copper as part
of their structure.
Many manufacturers of electronic equipment use copper because
it is more efficient in conducting electricity and it lasts
longer than other materials.
Copper may be closer to us than we think, either pure or
as part of alloys. It is present in coins, kitchen utensils,
jewelry, art objects, furniture, make up and paints, musical
instruments, clothes...
In transportation technology copper plays a very important
role. It is present in cars, planes, ships and even in space
vehicles. It is used in engines, electronic and electric systems.
A new car uses some 20 Kg of copper, two fold the 10 Kg that
it used in the 70´s. The copper wires included in a
luxury car measure more than 1.5 Km. And in the case of an
airplane, this length reaches as much as 100 Km.
Some properties of copper, such as the fact that it is a
good thermal conductor, strong, corrosion resistant and non-magnetic
make it ideal for alloys used in the manufacture of specialized
machinery and parts for industrial processes.
Copper is also used in compounds employed in agriculture,
for instance to compensate nutritional deficiencies in soils
and crop plants.
And in the future? Copper is compatible with the new technologies
that are being developed and which will require an element
that is reliable and efficient. After all we have already
used it for 10,000 years.
