Wire For Heating Elements
Cr15Ni60 is a type of Nichrome alloy wire. Nichrome is a family of
nickel-chromium-based alloys that are commonly used in various
heating and sensing applications.
Specifically, the Cr15Ni60 Nichrome alloy wire has the following
key characteristics:
Composition:
Chromium (Cr): Approximately 15%
Nickel (Ni): Approximately 60%
Iron (Fe): Remaining balance, typically around 25%
Other minor alloying elements may be present in small amounts.
Properties Of Cr15Ni60 Nichrome Alloy Wire:
1. Electrical Resistivity: The Cr15Ni60 Nichrome alloy has a
relatively high electrical resistivity, typically in the range of
1.00-1.10 ohm-mm²/m. This makes it suitable for use in heating and
sensing applications where a high-resistance material is required.
2. Oxidation Resistance: The chromium content provides good
oxidation resistance, allowing the Nichrome wire 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, making it suitable for use in applications
where sustained exposure to high temperatures 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 Nichrome wire
to be formed and shaped as needed.
Applications Of Cr15Ni60 Nichrome Alloy Wire:
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
The Cr15Ni60 Nichrome alloy wire is a versatile and widely used
material in industries where high-temperature, corrosion-resistant,
and high-resistance heating or sensing applications are required.
