The core element of the electric heating tube: electric heating wire

Electric heating wire is a common heating element and plays an important role in life. Its function is to generate heat after power-on and convert electrical energy into heat. The heating wire has a wide range of applications, and it has applications in medical, chemical, electrical, electronic and other industries.

Iron-chromium-aluminum alloy wire and nickel-chromium alloy wire are two commonly used heating wires. They have different functional characteristics. Let's take a look at the difference between iron-chromium alloy wire and nickel-chromium alloy wire.

The advantages and disadvantages of iron-chromium-aluminum alloy wire:

Advantages: high temperature, long service life, high surface load, good oxidation resistance and low price of iron-chromium-aluminum heating wire;

Disadvantages: high temperature strength is low, its plasticity increases as the use temperature increases, it is easy to deform in a high temperature environment, and it is not easy to repair after deformation.

The advantages and disadvantages of nickel-chromium alloy wire:

Advantages: high-temperature strength is higher than that of iron-chromium-aluminum, not easy to deform under high-temperature conditions, better plasticity, corrosion resistance, and long service life;

Disadvantages: The use temperature is lower than that of iron-chromium-aluminum alloy wire, but the price is several times higher than that of iron-chromium-aluminum alloy.
