- 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.
- Material Characteristics
1. Cr20Ni80 resistance wire has excellent electrical properties and
thermal stability, performing well in vacuum environments.
2. Its oxidation resistance and corrosion resistance make it
suitable for long-term stable operation in vacuum furnaces.
- Uniform Heating
1. Using Cr20Ni80 resistance wire as heating elements in vacuum
furnaces can achieve highly uniform heating effects.
2. Since there is no convection or conduction in a vacuum
environment, the uniform heating characteristics of the resistance
wire are crucial for ensuring the uniformity of materials during
heating.
- High Temperature Stability
1. Cr20Ni80 resistance wire can work stably at high temperatures
for extended periods, maintaining its resistance characteristics
and heating effects.
2. This makes Cr20Ni80 resistance wire an ideal heating element
material for vacuum furnaces, suitable for various high-temperature
treatment and sintering processes.
- Application Areas
1. Cr20Ni80 resistance wire is widely used in vacuum furnaces in
laboratories and industries for sintering, annealing, heat
treatment, and other processes.
2. In fields such as materials science, electronic materials, and
powder metallurgy, vacuum furnaces are important experimental and
production equipment, with Cr20Ni80 resistance wire being a key
component.
