Constantan wire is the first choice when low-temperature heating resistor materials are used for general electric heating elements and varistors. The performance of the constantan wire determines that the voltage of the constantan wire affects its resistance value. But we need to know what is the relationship between the voltage and resistance of the constantan wire in actual use, and what effect will happen.
Through the test, the resistivity of constantan wire generally cannot remain unchanged within a wide range of voltages. Under normal temperature conditions, the resistivity of constantan wire can remain unchanged in a lower voltage range. After a certain voltage is exceeded, the constantan wire voltage increases with the change of ion movement, and its resistivity will rapidly decrease.
Therefore, when the constantan wire material is used in different environments, the product needs to be selected according to the "Constantan Wire Technical Parameters". We need to know that resistance alloy materials have different classifications due to the elements contained in them and the temperature of use. Constantan wire and manganese copper wire are not a concept, we need "Correctly understand and use constantan wire and manganese copper wire". Of course, you can also directly choose "Constantan Wire Products Produced by Yancheng Songtai" to compare the quality of products with other manufacturers.
