Cr20Ni80 wire, also known as Nichrome 80/20 wire, is an alloy made from 80% nickel and 20% chromium. It is widely used in various industrial applications due to its high resistance to oxidation and corrosion, along with its ability to withstand high temperatures. This alloy wire is commonly utilized in heating elements, resistance wire, and other high-temperature applications.

Highlight: Heating Element Cr20Ni80 Resistance Wire, Heating Element Nichrome 80 Resistance Wire, 637MPA NiCr Alloy

High-Temperature Resistance:

Can withstand temperatures up to 1200°C (2192°F) in continuous service, making it ideal for use in high-temperature environments such as furnaces, kilns, and heaters.

Oxidation and Corrosion Resistance:

Exhibits excellent resistance to oxidation in both hot and cold environments, due to the formation of a protective chromium oxide layer.

Resists corrosion in various atmospheric conditions, including moist or humid environments, which extends the lifespan of the wire in demanding settings.

Electrical Resistivity:

Cr20Ni80 has a high electrical resistivity, around 1.09 µΩ·m at 20°C, making it ideal for use in resistance heating applications. The resistivity remains stable over a wide temperature range, ensuring consistent performance.

Mechanical Strength and Stability:

The wire has excellent mechanical strength at elevated temperatures, making it resistant to sagging, warping, or deformation under continuous high heat.

It also maintains good ductility, allowing it to be shaped, bent, or coiled without losing its structural integrity.

Thermal Expansion:

Exhibits moderate thermal expansion, ensuring that it does not expand or contract significantly when exposed to temperature fluctuations, which is critical for precise heating elements and applications.

Key Advantages of Cr20Ni80 Wire:

Consistent Resistance: Offers stable and predictable resistance across a wide range of temperatures.

Durability: Long lifespan due to its resistance to oxidation, corrosion, and thermal fatigue.

High Melting Point: Can handle extremely high temperatures without melting or degrading, making it suitable for demanding thermal applications.

Versatile: Used in a wide range of industries, including manufacturing, electronics, and laboratory environments.

Comparison to Other Alloys:

Compared to lower nickel-chromium alloys (like Cr15Ni60), Cr20Ni80 has better resistance to oxidation, a higher working temperature limit, and greater stability under high-heat conditions.

While more expensive than some alternatives, its longer lifespan and superior performance make it cost-effective in the long run for applications where reliability is crucial.
