Manufacturing process and application of alloy resistors

Alloy resistors are a common electronic component with stable resistance values, high accuracy, and good stability, and are widely used in electronic circuits. This article will focus on the manufacturing process and application fields of alloy resistors

1、 Manufacturing process of alloy resistors

1 Selection of raw materials

The main raw materials for alloy resistors include metals such as nickel, chromium, copper, and iron, usually with small amounts of alloying elements such as manganese and boron added. These metal raw materials are finely alloyed during the manufacturing process to ensure that the final product has the required resistance and performance

2 Material processing

In the manufacturing process of alloy resistors, the metal raw materials need to be melted first, and then the oxides and impurities on the surface of the metal materials are thoroughly removed through processing techniques such as rolling and drawing, ensuring the purity and uniformity of the material

3 Making resistors

After material processing, the alloy material is cut into pieces of a certain size, and then a thin film is coated on the resistance sheet through thin film technology to improve its stability and corrosion resistance

4 Adjusting the resistance value

In order to ensure that the resistance value of the alloy resistance meets the engineering design requirements, the resistance sheet will be sintered during the manufacturing process, and the resistance value will be adjusted by controlling temperature and time to ultimately achieve the required standards

5 Testing and Packaging

After adjusting the resistance value, the alloy resistance will be tested to ensure that its performance meets the standard requirements. Subsequently, the alloy resistor is packaged to protect it from external environmental influences and facilitate transportation and use
