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.
1. Cr20Ni80 resistance wire possesses excellent resistivity and
resistance temperature coefficient, capable of rapidly generating
high temperatures while maintaining stability.
2. Its high-temperature stability makes it an ideal heating
element, suitable for various applications in resistance heaters.
1. Resistance heaters utilizing Cr20Ni80 resistance wire can
achieve rapid and uniform heating effects.
2. The Cr20Ni80 resistance wire inside the heater quickly converts
electrical energy into heat, rapidly increasing the internal
temperature of the heater and enhancing heating efficiency.
1. Cr20Ni80 resistance wire is widely used in various resistance
heaters, including household electric heaters, industrial baking
equipment, and chemical processing equipment.
2. Whether it's clothes dryers, ovens, or industrial baking
furnaces, Cr20Ni80 resistance wire can be found, providing stable
and reliable solutions for various heating needs.
