High Resistance Heating Alloy-Enhancing Resistance Accuracy through Precision Thickness Control

In the realm of electrical conductivity, precision is paramount. The accuracy of resistance alloy thickness directly impacts the overall resistance precision. At Shijiazhuang Chengyuan Alloy Material Co., Ltd., we take this aspect to heart, ensuring a meticulous approach to achieving impeccable thickness accuracy.


Utilizing Varied Rolling Mills for Diverse Applications

One of the cornerstones of our commitment to resistance accuracy is our utilization of different rolling mills tailored for specific applications. Each rolling mill is optimized to meet the unique requirements of various projects. This strategic approach enables us to deliver consistent and reliable results.


Advanced Thickness Control for Fine-Tuned Resistance Values

Our dedication to precision doesn't stop at the choice of rolling mills. We go a step further by employing advanced thickness control capabilities. This sophisticated technology empowers us to fine-tune conductor resistance values with utmost precision. By having the ability to make minute adjustments, we ensure that your electrical components perform optimally.


Unraveling the Science of Resistive Alloys

While all metals have the capacity to conduct electricity, the ease with which electricity flows through a specific metal, known as conductivity, depends on its chemical composition and other intrinsic factors. Resistive alloys are engineered to modify the flow of electrical current, impeding its progress deliberately.


The Heat Equation: A Crucial Aspect

It's important to understand that when electricity courses through an object, it generates heat. This phenomenon is explained by the following equation:

Q = RI^2T


  • Q: Calorific value (Joules)
  • R: Resistance (Ohms)
  • I: Current (Amperes)
  • T: Time (Seconds)

As per this equation, it's evident that the higher the resistance (R), the greater the amount of heat (Q) emitted. This revelation underscores the significance of selecting the right materials for applications where heat generation is a crucial requirement.


Nickel Chromium Alloy for Electric Heating (JIS C 2520)

Nickel chromium alloy stands out as a preferred choice for electric heating applications due to its exceptional attributes. It boasts excellent oxidation resistance and high-temperature strength, making it a reliable option for a wide range of scenarios. However, it's worth noting that the use of this alloy in sulfide gases and hot, humid reducing atmospheres should be avoided for optimal performance.


Iron-Chromium Alloy for Electric Heating (JIS C 2520)

For applications requiring high-temperature performance, the iron-chromium alloy comes to the forefront. While it exhibits good oxidation resistance, it's essential to acknowledge that its high-temperature strength doesn't match that of nickel-chromium alloy for electric heating. Therefore, careful consideration of the specific operational conditions is advised when opting for this alloy.


Factors Influencing Heat Generation

The production of heat in electrical components is influenced by several factors, including:

  1. Product Dimensions: Both thickness and width of the material play a critical role in determining the amount of heat generated.

  2. Volume Resistivity (ρ): This property characterizes the material's resistance to the flow of electrical current.

  3. Resistance Increase Factor: Understanding how resistance changes under varying conditions is vital for precise heat control.
