Boost Your Business With Nichrome Alloy Cr20Ni80 Wire For
Industrial Applications
Introduction:
Cr20Ni80 alloy wire is a commonly used nickel-chromium alloy wire,
also known as NiCr 80/20 alloy wire.
1. Composition: The chemical composition of Cr20Ni80 alloy wire
mainly contains 20% chromium and 80% nickel. This alloy wire has a
high nickel content, giving it good resistance to high temperatures
and corrosion.
2. 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.
3. 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.
4. Mechanical properties: Cr20Ni80 alloy wire has good mechanical
properties, including strength and ductility. It can be plastically
deformed and adjusted through cold working and heat treatment.
Common processing techniques include drawing, rolling and bending.
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.
