Resistance Flat Wire Robbin
CR15Ni60 is a nickel-chromium-based alloy ribbon that is commonly
used for various heating and sensing applications. The alloy
composition consists of approximately 15% chromium and 60% nickel,
with the remaining percentage being iron and other minor alloying
elements.
The key properties of CR15Ni60 ribbon include:
1. High Electrical Resistivity: The alloy has a relatively high electrical resistivity, typically
in the range of 1.00-1.10 ohm-mm²/m, making it suitable for use in
heating and sensing applications.
2. Excellent Oxidation Resistance: The chromium content provides good oxidation resistance, allowing
the ribbon to operate at high temperatures without significant
degradation.
3. High-Temperature Strength: The combination of chromium and nickel provides the alloy with
excellent high-temperature strength and creep resistance, enabling
its use in applications where sustained high-temperature exposure
is required.
4. Corrosion Resistance: The nickel content contributes to the alloy's corrosion
resistance, making it suitable for use in environments with
moderate to high corrosive conditions.
5. Ductility: The nickel-rich composition of the alloy provides a good balance
of ductility and strength, allowing the ribbon to be formed and
shaped as needed.
Applications of Cr15Ni60 Ribbon:
1. Heating elements for electric furnaces, ovens, and other
high-temperature equipment.
2. Sensing elements for temperature measurement, such as in
thermocouples and resistance temperature detectors (RTDs).
3. Heating components in industrial and domestic appliances.
4. Resistor elements in electronic circuits and devices.
5. Catalytic converters in automotive exhaust systems.
