Industry information

Ahead of us to understand the classification and function of electric hotline, hair hotline characteristics, today we're going to see the heating wire which we didn't know before! Heating wire what are the two basic categories?

 

Heating wire is a common heating elements, plays an important role in people's life, iron chromium aluminum alloy heating wire and nickel chromium alloy heating wire is the most commonly used two kinds of heating wire, they each have each advantages and defects, give you specific summarized below to explain in detail:

 

1. The iron chromium aluminum alloy heating wire

 

Advantages of iron chromium aluminum alloy heating wire: operating temperature is high, the experiment of iron chromium aluminum alloy heating wire temperature to 1400 ℃. The use of iron chromium alloy heating wire, long life, high resistivity, high surface recombination, and has good oxidation resistance.

 

Iron chromium aluminum alloy heating wire drawback: under the environment of high temperature strength is low, with the increase of temperature the plasticity of iron chromium alloy heating wire will increase, that is to say, iron chromium aluminum alloy heating wire easily occur in the high temperature deformation, and after the deformation is not easy to repair.
 

2. The nickel chromium alloy heating wire

 

Nickel-chromium alloy heating wire: the advantages of high intensity in the environment of high temperature, high temperature operation for a long time not easy deformation, not easy to change the structure, and nickel chromium alloy heating wire temperature plasticity is good, repair after deformation is relatively simple. In addition, the emissivity of nickel-chromium alloy heating wire is high, with no magnetic, good corrosion resistance, long service life.

 

The disadvantage of nickel-chromium alloy heating wire: operating temperature cannot reach the level of a heating wire. Nickel-chromium alloy heating wire manufacturing needs to use nickel, the metal price is higher than the price of iron, chromium, aluminum, so a nickel-chromium alloy heating wire manufacturing costs is higher, is not conducive to cost control.

 

Above is the two basic categories of basic analysis of heating wire, the electric heating wire, if you have any questions or want to know more about electric wire or electric hotline information do not hesitate to contact with us!
