Nichrome wire, such as Ni80Cr20 wire, finds applications in various
industries and products due to its unique properties. Some common
applications of Nichrome wire include:
Heating Elements: Nichrome wire is widely used in heating elements
for electric ovens, toasters, space heaters, industrial furnaces,
and other heating appliances due to its high electrical resistance
and ability to generate heat efficiently.
Resistors: It is used in resistors for regulating electrical
current and voltage in electronic circuits.
Industrial Furnaces: Nichrome wire is used in industrial furnaces
for high-temperature applications due to its excellent oxidation
resistance and durability at elevated temperatures.
2. High temperature performance: Cr20Ni80 alloy wire can work
stably in high temperature environments. It has a high melting
point and good oxidation resistance, and can withstand high
temperature environments in high temperature heating and heating
element applications, with a maximum use temperature of up to 1200
degrees Celsius.
3. Resistivity: Cr20Ni80 alloy wire has moderate resistivity,
making it a commonly used resistance wire material. Its resistivity
is usually in the range of 1.09-1.12 μΩ·m and can be adjusted as
needed.
4. Corrosion resistance: Cr20Ni80 alloy wire shows good corrosion
resistance in common acid and alkali media. It can resist corrosion
by acids and alkalis of general concentrations, but it still needs
to be used with caution in special corrosive media.
