How many degrees is the temperature of the heating wire when working?
The accurate name of the heating wire should be called resistance wire, which is an alloy made of iron mixed with nickel, chromium, tungsten and other metals, and will heat up due to resistance when electricity is applied.
The resistance wire basically does not change below 200 degrees Celsius, but it will appear white due to the evaporation of surface water.
At 200-400 degrees Celsius, the resistance wire will start to blush.
At 400-700 degrees Celsius, the resistance filament will be slightly blackened due to surface oxidation, and gradually glow and turn red.
At 700-1400 degrees Celsius, the resistance filament will begin to emit a strong glow, and the color will gradually change from dark red to orange-white.
Above 1400 degrees, most resistance wires will melt or even burn and evaporate.
If it is tungsten alloy, it can reach about 3000 degrees in the absence of air, and at this time, it will emit hot orange-white light.
Above 3000 degrees, only special alloys can be, and generally no one uses them as resistance wires.
