The major applications of copper are electrical wire (60%), roofing
and plumbing (20%), and industrial machinery (15%). Copper is used
mostly as a pure metal, but when greater hardness is required, it
is put into such alloys as brass and bronze (5% of total use). For
more than two centuries, copper paint has been used on boat hulls
to control the growth of plants and shellfish. A small part of the
copper supply is used for nutritional supplements and fungicides in
agriculture. Machining of copper is possible, although alloys are
preferred for good machinability in creating intricate parts.
Integrated circuits and printed circuit boards increasingly feature
copper in place of aluminium because of its superior electrical
conductivity; heat sinks and heat exchangers use copper because of
its superior heat dissipation properties. Electromagnets, vacuum
tubes, cathode ray tubes, and magnetrons in microwave ovens use
copper, as do waveguides for microwave radiation.
