Nickel-Chrome 60 is the world’s
standard of comparison in the
electrical trade for metallic
resistance wire. It is an alloy of 60%
nickel and 16% chromium, and is
the accepted material for heating
devices operating up to 1000°C
(1850°F). This encompasses
most pluggable power cord
domestic heating appliances and
those heating units of medium
temperatures which do not require
the unsurpassed quality of
NI/CR-80/20, the 80-20 alloy.

In addition to being commonly used
in electrical heating, Nickel-Chrome
60 is used extensively in industrial

applications for rheostats
and resistance units. It
makes for compact units
capable of withstanding severe
overloads and short circuits without
damage or circuit impairment.

The excellent corrosion resistance
of Nickel-Chrome 60 makes it very
useful for purposes other than
electrical heating. Acid dipping
baskets, cyanide hardening and
pickling containers, filter cloth, wire
mesh, bolts and nuts are a few
representative uses.
