Application:
Cr20Ni80 alloy wire is widely used in many fields due to its
special properties and chemical composition. Here are some common
application areas:
1. Resistance heater: Cr20Ni80 alloy wire is widely used in the
field of resistance heaters to manufacture electric heating wires,
electric heating tubes and electric heating elements. It has good
high temperature resistance, can be heated quickly at high
temperatures, and is used to heat media such as air, liquids and
solids.
2. Industrial heaters: Cr20Ni80 alloy wire is also commonly used in
various industrial heaters, including hot blast furnaces, heat
treatment equipment, dryers, furnaces and heat exchangers. Its high
temperature stability and corrosion resistance make it an ideal
heating element material.
3. Temperature sensor: Since the resistance value of Cr20Ni80 alloy
wire changes with temperature, it is often used as a material for
temperature sensor elements. Based on the principle of resistance
measurement, the temperature change can be determined by measuring
the resistance value of Cr20Ni80 alloy wire.
4. Resistance wire: Cr20Ni80 alloy wire can also be used to make
various resistance wires for applications such as resistors,
electronic components and circuits. By controlling the length and
cross-sectional area of the alloy wire, the resistance value of the
resistance wire can be adjusted to meet specific circuit
requirements.
5. Experiments and research: Due to its stability and
controllability, Cr20Ni80 alloy wire is widely used in laboratory
research, academic research and development fields. It can be used
to simulate high temperature environments, electrothermal
experiments and material performance testing, etc.
