Ni80cr20 Nichrome Wire Nickel Chromium Electric Resistance Wire
Heating Element Wire
Introduction:
1. Ni80Cr20 wire is a type of resistance wire that is commonly used
in heating elements, resistors, and various electrical
applications. It is made up of 80% nickel and 20% chromium, which
gives it high electrical resistance and excellent oxidation
resistance at high temperatures. Ni80Cr20 wire is known for its
stability, durability, and ability to withstand high temperatures,
making it suitable for use in a wide range of industrial and
commercial applications.
2.Mechanical properties of ni80cr20 wire
Ni80Cr20 wire, also known as Nichrome 80/20, has the following
mechanical properties:
Tensile Strength: Ni80Cr20 wire typically has a high tensile
strength, which means it can withstand pulling forces without
breaking easily.
Elongation: It has a moderate elongation, allowing it to stretch
slightly under tension before breaking.
Hardness: Ni80Cr20 wire is known for its hardness, which
contributes to its durability and resistance to deformation.
Ductility: It exhibits good ductility, meaning it can be drawn into
wires or other shapes without breaking.
These mechanical properties make Ni80Cr20 wire a popular choice for
applications where strength, durability, and resistance to high
temperatures are required.
3. High temperature performance: Cr20Ni80 alloy wire can work
stably in high temperature environments. It has a high melting
point and good oxidation resistance, and can withstand high
temperature environments in high temperature heating and heating
element applications, with a maximum use temperature of up to 1200
degrees Celsius.
4. Resistivity: Cr20Ni80 alloy wire has moderate resistivity,
making it a commonly used resistance wire material. Its resistivity
is usually in the range of 1.09-1.12 μΩ·m and can be adjusted as
needed.
5. Corrosion resistance: Cr20Ni80 alloy wire shows good corrosion
resistance in common acid and alkali media. It can resist corrosion
by acids and alkalis of general concentrations, but it still needs
to be used with caution in special corrosive media.
