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.
