PTFE/PFA Insulated Heating Wire Cr20Ni80 Alloy Resistance Wire For Vacuum Furnaces

  • 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.
