Specific Applications
- Heating elements: Cr15Ni60 is widely used in the manufacture of heating elements, especially in periodic heat treatment furnaces below 900°C. It has good oxidation resistance and thermal strength at high temperatures, and can maintain its performance for a long time.
- Heating wire: Due to its high nickel content, Cr15Ni60 has excellent resistance and heat resistance, so it is often used in high-end electric heating tubes and high-end household electric heaters.
- Resistance band: In high-quality resistance boxes, Cr15Ni60 can be used as a resistance band, providing stable resistance values and good heat resistance.
- Chemical equipment: In the chemical industry, the alloy is used to manufacture high-temperature and corrosion-resistant equipment and pipelines, especially in acidic or sulfur-containing atmospheres, where its corrosion resistance makes it an ideal choice.
- Aerospace: In the aerospace field, Cr15Ni60 is used to manufacture high-temperature components of engines, which can withstand extreme temperatures and pressures due to its good oxidation resistance and heat resistance.
Advantages and Characteristics
- High temperature adaptability: The melting point of Cr15Ni60 Wire is about 1390℃, and it can operate stably in the temperature range of 800℃ to 1200℃. Its resistance performance remains stable at high temperatures, making it an ideal choice for high-temperature operating environments.
- Low expansion coefficient: The linear expansion coefficient of Cr15Ni60 Wire is about 17.0×10^-6/°C (in the temperature range of 20°C to 1000°C), which means that even when the temperature fluctuates, the dimensional change of the alloy is small, which helps to reduce structural problems caused by thermal stress and enhance the reliability of the equipment.
- Excellent mechanical properties: The tensile strength of Cr15Ni60 Wire is not less than 600 Mpa, and the elongation is at least 20%. Such mechanical properties ensure its stability when subjected to force, and it is not easy to undergo plastic deformation. At the same time, it is also easy to form during processing to meet diverse manufacturing needs.
- Processing convenience: Cr15Ni60 Wire exhibits good plasticity at room temperature, which is convenient for cold processing, such as stretching, bending and stamping. It can be easily made into components of various shapes and sizes, providing convenience for customized production.

Related Questions and Answers
Q: What are the physical properties of Cr15Ni60 Wire?
A: The resistivity of Cr15Ni60 Wire is about 1.25×10⁻⁶Ω·m, the melting point is about 1370°C, the applicable temperature range is 700°C to 1100°C, and the linear expansion coefficient is about 17.0×10⁻⁶/°C (20°C-1000°C).
Q: What are the mechanical properties of Cr15Ni60 Wire?
A: The tensile strength of Cr15Ni60 Wire at room temperature is ≥600MPa, and the elongation is ≥20%. At high temperatures, especially in high temperature environments around 1000°C, it can still maintain good mechanical strength and resistivity.
Q: What is the oxidation resistance of Cr15Ni60 Wire?
A: Cr15Ni60 Wire exhibits excellent oxidation resistance in high temperature environments. The increase in chromium content enables the alloy to form a stable oxide layer in an oxidizing atmosphere, effectively preventing further oxidation of the alloy itself. The oxidation rate at 1000°C is extremely low, and it can work in high temperature environments for a long time without losing performance.
