- Cr20ni80 Heating Resistance Wire
In resistance heaters, Cr20Ni80 resistance wire is a commonly used heating element material. It is composed of 20% chromium and 80% nickel, with excellent electrical resistance characteristics and high temperature stability, suitable for various heating applications.
- Applications in Laboratory and Scientific Research
1. Resistance Heaters: Cr20Ni80 resistance wire is commonly used in laboratory resistance
heaters to heat laboratory equipment, samples, or reaction vessels,
providing precise temperature control for various experiments.
2. Heating Elements in Vacuum Furnaces: Due to its excellent high-temperature stability, Cr20Ni80
resistance wire is often used as heating elements in vacuum
furnaces for high-temperature experiments and materials processing
in laboratories.
3. Thermocouples: Cr20Ni80 resistance wire can also be used as one of the thermal
sensing elements in thermocouples, used for measuring temperature
and temperature changes, which are crucial for temperature
monitoring and control in laboratory settings.
4. Material Performance Testing: In scientific research, Cr20Ni80 resistance wire can be used as part of material performance testing to assess thermal properties such as thermal conductivity, coefficient of thermal expansion, and other thermal characteristics.
