Advantages and disadvantages of iron-chromium-aluminum alloy heating wire
The advantage of the iron-chromium-aluminum alloy heating wire is that the operating temperature is high. The experimental results show that the maximum operating temperature of the iron-chromium-aluminum alloy heating wire can reach 1400 °C. The iron-chromium-aluminum alloy heating wire has long service life, high electrical resistivity, high surface composite, and good oxidation resistance.
The disadvantage of the iron-chromium-aluminum alloy heating wire is that the strength in the high-temperature environment is low, and the plasticity of the iron-chromium-aluminum alloy heating wire is enhanced with the increase of the temperature, that is, the iron-chromium-aluminum alloy heating wire is easily deformed at a high temperature. And it is not easy to repair after deformation.
Advantages and disadvantages of nickel-chromium alloy heating wire
The advantage of nickel-chromium alloy heating wire is high strength in high temperature environment, long-term high temperature operation is not easy to deform, and it is not easy to change the structure, and the nickel-chromium alloy heating wire has good room temperature plasticity, and the repair after deformation is relatively simple. In addition, the nickel-chromium alloy heating wire has high emissivity, no magnetic property, good corrosion resistance and long service life.
A disadvantage of the nickel-chromium alloy heating wire is that the operating temperature cannot reach the level of the previous heating wire. Nickel-chromium alloy heating wire is required to use nickel. The price of this metal is higher than that of iron, chromium and aluminum. Therefore, the manufacturing cost of nickel-chromium alloy heating wire is high, which is not conducive to cost control.
In recent years, the country's investment in industrial industries, electrical appliances, and automobiles has been increasing, and it has gradually driven the development of related heating pipe industries, making the heating pipe enterprises a good applause. At the same time, we must also clearly understand that the guaranteed growth of the entire industry does not mean that all the heating pipe companies can be safe. In order to meet the needs of the industry growth, domestic heating pipe enterprises must actively adjust the product structure and achieve strategic transformation. Starting from the direction of specialization, clustering and grouping, we will explore the creative value of enterprises and gradually develop into brand advantages to achieve different market occupations in different fields of low, medium and high.
