HISTORICAL BACKGROUND
 
    Copper is the 1st metal used by man in a sighnificant quantity.  This was due to its easy usability; its flexibility allowed it to be transformed into required shapes and sizes for desired tasks.  Copper is principle known for its strength, durability, and ability to resist corrosion.  The principle alloys of copper is bronze and brass.  Bronze was first founded when workmen found by hammering copper you could harden it and by heating it you could melt it.  By adding small amounts of tin, copper's durability was matched.  This new material was found to be harder and easier to cast then copper although it was liable to fracture if not made properly.  This new material started the Bronze Age.
    The first source of supply known was mined out of the mountainous country around Lake Van in Armenia by the Sumerians.  Copper was mined in Egypt and elswhere for many years.  For majority of  the 19th century Britain was the major producer.  This was the case until mines were also found in USA, Chile, and later in Africa.  In 1911, the world's output exceeded 1 million tons per year.  New developments have occured with the advances in metallurgical knowledge.  New copper alloys have been established usable in even todays world.  Since then, other developments have happend in the world to increase copper's role such as use of electrical power.  Today the world's output of copper is greater then 5 million tons/year.
    Uses of copper have been created and established in industry over the years as far back as the Stone Age.  In Egyptian ancient times, due to its ductility, it was used for water piping.  As time progressed, it was also used for heating.  Due to its ability to resist corrosion, many buildings have used copper for roofing.  Because of copper's electrical conductivity, it has been used for electrical wiring (i.e. telephone).  Other future and present day uses are solar heat, desalination of H2O, and linear motors.

INDUSTRIAL APPLICATIONS
Copper wiring is used in numerous machines, tools and buildings as an electrical transferal device providing optimum power transfer with minimum resistance and heat.

With the numerous power demands that are plaging our homes and offices, large amounts of energy is being used.   If  wiring (other than copper) is being used , a large percentage of the electricity being payed for is being converted to heat along the electrical wiring in the walls and  the machine.
Because copper has the lowest resistance for electrical transfer, a large amount of energy savings and a reduction in heat will result with its use.

Copper wiring in homes is the only wiring approved by all electrical codes accross the United States and Canada.  The High melting point of copper enables it to take heavly loads and current surges without breaking down.Copper wire is smaller in diameter than non-copper wiring and non-copper wiring requires a non-oxidative coating. Because Copper Oxide conducts electricity a non-oxidative coating is not required.  When in use  (Load, no-load) conditions can cause non-copper materials to loosen from fastenings and thus loose connections, heat up and arc dangerously.
