Product Description

 Ni40cr20 NiCr 40/20 Heating Wire Nichrome Resistance Wires Nicr Heating Wire

NI40Cr20 is a type of high-temperature resistant alloy that consists of 40% nickel and 20% chromium. It is also known as Nichrome 40 or NiCr 40/20. This alloy offers excellent resistance to high temperatures, corrosion, and oxidation.

NI40Cr20 wire is a common application of this alloy. The wire is often used as an electrical resistance wire in various heating applications, such as in heating elements for industrial furnaces, ovens, and appliances. The wire can also be used in electronic components such as heating coils, resistors, and heating pads.

NI40Cr20 wire has a high melting point of around 1200°C (2192°F) and can maintain its strength and stability even at temperatures above 800°C (1472°F). It also has good mechanical properties, such as high tensile strength and good ductility, which make it easy to form and shape.

The specific properties of the NI40Cr20 wire, such as its diameter, resistivity, and temperature coefficient of resistance, would depend on the intended use and the specific requirements of the project. The wire may be customized to meet the specific needs of the application, such as the required temperature range, power output, and environmental conditions.

Overall, NI40Cr20 wire is a valuable material for various high-temperature heating applications that require resistance to corrosion, oxidation, and high temperatures.
