Our nickel-chromium alloy resistance heating wire is now available
coiled for ready use. Coiled heating wire is used in many
high-temperature applications, including electric furnaces,
radiant heating, and air heating.
NIC80
is an alloy of 80% nickel and 20% chromium and represents
the highest standard in materials for use in elevated temperature
environments. It is useable at temperatures up to 1150°C (2100°F).
NIC60 contains 60% nickel and 16% chromium, with the
balance iron, and can be used up to 1000°C (1850°F). It is
the benchmark material, most widely accepted and employed
in electrical heating.
Both of these alloys also provide excellent
corrosion resistance.
Coils using 18 to 30 AWG wire with 25 to 100 turns per inch
are standard. Custom coil dimensions are also available.

CAUTION AND WARNING!
Spools
of wire are supplied tightly compacted. Never use precoiled wire without
extending to at least three times the compacted (spooled) length.
Fully-extended
wire (Model No. NIC80-020-125) is 16.5 times the "as supplied" coiled
length
