Cr20Ni80 alloy wire is a high-resistance alloy wire composed of 20%
chromium and 80% nickel. It has high resistivity and good oxidation
resistance, and is suitable for high-temperature heating, electric
furnace heating, electric heating devices and other applications.
This alloy wire is widely used in industrial heating and electric
heating fields.
Cr20Ni80 alloy wire is very suitable for manufacturing electric
heating wires due to its high temperature stability and resistance
temperature characteristics. Heating wire is a filament-shaped
heating element that can heat quickly in high temperature
environments. Cr20Ni80 alloy wire is often made into electric
heating wire by winding or braiding.
When manufacturing electric heating wire, Cr20Ni80 alloy wire is
usually wound into a thin diameter or braided into a filament-like
structure. This filament-like structure allows the electric heating
wire to create a larger surface area, thereby improving heat
transfer efficiency. By energizing the electric current through the
Cr20Ni80 alloy wire, the resistance heating effect converts
electrical energy into thermal energy, causing the electric heating
wire to heat up rapidly.
Heating wires are widely used in various fields, including
industrial heaters, household appliances, experiments and research,
etc. They can be used to heat air, liquid and solid media to
achieve functions such as heating, drying, heat treatment and
laboratory temperature control.
