Nichrome alloy tube is a type of metal tube made from a nickel-chromium alloy.
It is known for its high resistance to heat and corrosion, making it a popular choice for use in high-temperature applications such as heating elements, furnaces, and industrial ovens.
The alloy typically contains around 80% nickel and 20% chromium, with small amounts of other metals added to improve its properties.
Nichrome alloy tubes are available in a range of sizes and thicknesses to suit different applications.

Ni80Cr20 tube
The resistance of the nichrome tube generates heat when an electric current passes through it.
The heat generated by the nichrome tube is proportional to the amount of electrical current flowing through it and the resistance of the tube.
The higher the electrical current and the resistance of the tube, the more heat is generated.

Ni80Cr20 tube
Characteristics: Stable performance; Anti-oxidation; Corrosion resistance; High temperature stability; Excellent coil-forming ability; Uniform and beautiful surface condition without spots.

Nichrome tubes can be manufactured in various shapes and sizes to suit different applications.
They can be straight or coiled, and can be made with varying diameters and lengths.
The thickness of the tube and the alloy composition can also be tailored to meet specific heating requirements.

Ni80Cr20 tube Usage: Resistance heating elements; Material in metallurgy; Household appliances; Mechanical manufacturing and other industries.
