Cr15Ni60/60Ni16Cr/NiCr6015 Nickel-Chromium-Iron Alloys The Top-Notch Material for Heating Element Resistor

Cr15Ni60/60Ni16Cr/NiCr6015 Nickel-Chromium-Iron Alloys The Top-Notch Material for Heating Element Resistor

Main characteristics of Ni-Cr and Ni-Cr-Fe electric heating alloys

Some key features of Cr15Ni60 include:

1. Chemical Composition: Cr15Ni60 is composed primarily of chromium (15%) and nickel (60%), with the remainder being iron and trace amounts of other elements like manganese and silicon
2. High-Temperature Resistance: The alloy exhibits excellent resistance to high temperatures, with a melting point of around 1390°C and capable of withstanding continuous use up to 1100°C
3. Oxidation Resistance: Thanks to the chromium content, Cr15Ni60 forms a stable chromium oxide (Cr2O3) layer at high temperatures, which protects the alloy from further oxidation
4. Mechanical Strength: Cr15Ni60 maintains good mechanical strength at high temperatures, with a tensile strength of approximately 600 MPa at room temperature, and it retains strength even at elevated temperatures
5. Electrical Resistivity: The alloy has a high electrical resistivity of about 1.11 Ω·mm²/m, which is beneficial for applications requiring high resistance at lower voltages
6. Thermal Stability: Cr15Ni60 demonstrates good thermal stability, with a low temperature coefficient of resistance, ensuring stable resistance values across a wide temperature range
7. Corrosion Resistance: The alloy shows good general corrosion resistance, especially in oxidizing environments, due to the formation of a passive oxide layer
8. Physical Properties: Cr15Ni60 has a density of 8.2 g/cm³ and a thermal expansion coefficient of 13.0×10⁻⁶/°C (20-1000°C), which contributes to its dimensional stability at high temperatures

These characteristics make Cr15Ni60 an ideal material for high-temperature electrical heating elements, industrial furnace components, and other applications where high-temperature stability and resistance are required.

Applications:

• Heating Elements: Ideal for use in periodic heat treatment furnaces operating below 900°C.
• High-End Electric Heating Devices: Used in high-quality electric heating wires for appliances.
• Resistance Boxes: Employed in high-quality resistance boxes for precise electrical measurements.

Overall, Cr15Ni60 is a reliable choice for high-temperature applications requiring stable electrical resistance and excellent corrosion resistance.
