is everywhere take a minute and look around you, its in what you see and
often in what you dont see. Its behind the walls of your home, in electrical
and telephone wiring. Its in computers, refrigerators, microwaves and automobiles.
The average home today contains about 400 pounds of copper for
electrical wiring, water pipes and appliances, while the automobile you drive contains
about 50 pounds. Each child born today in America will need 1500 pounds of copper in the
course of his or her lifetime to enjoy our current standard of living.
Copper is the most versatile and durable of all metals and has been
called "mans eternal metal". Copper is malleable, ductile and long
lasting. Copper is a better conductor of heat and electricity than any other metal except
silver. Without copper, there might never have been an electric light or space flight.
This miraculous mineral and its alloys are at the heart of all technology, from
telecommunications to transportation.
Copper Consumption Copper and copper alloy
products used in building construction, such as electrical wire and power cables, water
pipes, plumbing fixtures, roofing materials and brass furnishings account for 40% of the
annual consumption of copper. Electric and electronic products account for 25%; industrial
machinery and equipment account for 12%; transportation equipment uses 13% and consumer
and general products account for 10%.
Did you know? When zinc is alloyed
with copper, brass is made. And when tin is alloyed with copper, bronze is made. Both
brass and bronze are stronger than pure copper and do not corrode in air or water except
for a small amount of tarnishing.
Home Furnishings Your refrigerator,
dishwasher, microwave, washing machine and clothes dryer are just a few of
the laborsaving devices in your home that contain copper. Entertainment components such as
your VCR, television, stereo and computer equipment are all dependent upon copper. Copper
is alloyed with zinc to form brass, which increases the strength and castability, imparts
an appealing golden color, and is used in door knobs, light fixtures and home décor
Did you know? Todays U.S.
coins, dimes, quarters and half dollars have a solid copper core and an outer layer of a
Copper Fact The Statue of Liberty contains
179,000 pounds of copper. After one hundred years of enduring biting sea winds, driving
rains and the beating sun, the copper skin of the Statue of Liberty not only has grown
more beautiful, it has remained virtually intact. The weathering and oxidation of the
copper skin has amounted to just .005 of an inch in a century.
Coppers Future One of coppers
major advantages is that it is recyclable. In North America alone, approximately one half
of the copper consumed annually comes from recycled material. Coppers recycle value
is so great that premium-grade scrap has at least 95% of the value of primary copper from
newly mined ore.
