Contact SupplierNICKEL-BASE ALLOYS have a number of
unique properties, or combinations of properties,
that allow them to be used in a variety of
specialized applications. For example, the high
resistivity (resistance to flow of electricity) and
heat resistance of nickel-chromium alloys lead
to their use as electric resistance heating elements.
The soft magnetic properties of
nickel-iron alloys are employed in electronic
devices and for electromagnetic shielding of
computers and communication equipment. Ironnickel
alloys have low expansion characteristics
as a result of a balance between thermal expansion
and magnetostrictive changes with
temperature. Originally used as clock pendulums,
these alloys are now widely employed as
lead frames in packaging electronic chips and
as the shadow-masks in color television tubes.
On a larger scale, they provide one solution to
coping with the thermal expansion requirements
of storage and transportation tanks for
the growing liquid natural gas industry.
Other properties of interest that expand the
markets and applications of nickel and nickel
alloys include those to follow:
� Shape memory characteristics of equiatomic
nickel-titanium alloys that allow them to be
used as actuators, hydraulic connectors, and
eyeglass frames
� The high strength at elevated temperature
and resistance to stress relaxation that allow
wrought nickel-beryllium-titanium to be
used for demanding electrical/electronic applications,
for example, springs subjected to
elevated temperatures (up to 370 °C, or 700
°F) for short times
� The combination of heat removal (high thermal
conductivity) and wear resistance that
allows cast nickel-beryllium-carbon alloys
to be used for tooling for glass forming operations.
Resistance heating alloys are used in many
varied applications�from small household appliances
to large industrial process heating systems
and furnaces. In appliances or industrial
process heating, the heating elements are usua
