Advantages and disadvantages of imported electric heating wires

Advantages and disadvantages:

1. The main advantages and disadvantages of the iron chromium aluminum alloy series are: advantages: the iron chromium aluminum electric heating alloy has a high operating temperature, with a operating temperature of up to 1400 degrees (0Cr21A16Nb, 0Cr27A17Mo2, etc.), long service life, high surface load, good oxidation resistance, high resistivity, and low price. Disadvantages: Mainly due to low high-temperature strength, its plasticity increases with the use temperature, and the components are prone to deformation, making it difficult to bend and repair.

2. The main advantages and disadvantages of the nickel chromium electric heating alloy series are: advantages: high temperature strength is higher than that of iron chromium aluminum, it is not easy to deform under high temperature use, its structure is not easy to change, its plasticity is good, it is easy to repair, its radiation rate is high, it is non-magnetic, has strong corrosion resistance, and has a long service life.

Disadvantages: Due to the use of scarce nickel metal materials, the price of this series of products is several times higher than that of iron chromium aluminum, and the usage temperature is lower than that of iron chromium aluminum.

Advantages and disadvantages:

Firstly, we need to know that the red hot state of the electric heating wire is related to its structure. Let's first remove the hair dryer and take a section of the heating wire. Using an 8V 1A transformer, the resistance value of the heating wire or electric blanket's heating wire should not be less than 8 ohms, otherwise the transformer is prone to burning. Using a 12V 0.5A transformer, the resistance value of the heating wire should not be less than 24 ohms, otherwise the transformer is also prone to burnout. If the electric heating wire reaches a red hot state, the redder the better. An 8V 1A transformer should be used, which has a higher power than a 12V 0.5A transformer. This way, we can also better test the advantages and disadvantages of the electric heating wire.

Iron chromium aluminum or tungsten molybdenum electric heating alloy wires are tightly wound and can be used vertically. The surface is treated with insulation, oxidation resistance, and self diffusion prevention. The surface has good insulation and oxidation resistance, almost no oxidation at rated power temperature, and no nickel chromium oxide pollution.
