Nichrome (NiCr, nickel-chrome, chrome-nickel, etc.) is any of
various alloys of nickel, chromium, and often iron (and possibly
other elements). The most common usage is as resistance wire,
though they are also used in some dental restorations (fillings)
and in a few other applications.
When heated to red-hot temperatures, nichrome wire develops an
outer layer of chromium oxide,which is thermodynamically stable in
air, is mostly impervious to oxygen, and protects the heating
element from further oxidation.
Nichrome is used in the explosives and fireworks industry such as
electric matches and model rocket igniters.
Industrial and hobby hot-wire foam cutters use nichrome wire.
Nichrome wire is commonly used in ceramic as an internal support.
Nichrome wire is used for its ability to withstand the high
temperatures that occur when clay work is fired in a kiln.
Nichrome wire can be used as an alternative to platinum wire for
flame such as sodium, potassium, copper, calcium, etc.
The alloy price is controlled by the more expensive nickel content.
