Constantan

 

Constantan is a type of resistance alloy, which is made up of copper and nickel as the main components.

It has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500°C). It has good properities on mechanical working, high resistance of corrosion. It is used for variable and strain resistance of corrosion. It is used for variable and strain resisitance elements in alternative instruments.

 

resistance alloy constantan wire material: Constantan, CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi40 (6J40), CuNi44. 

 

Constantan  alloy characteristic

 

Constantan has a number of special characteristics due to which it is known as the most versatile alloy that is available.  Some of its important characteristics are:

 

  • High specific heat resistance
  • Negligible temperature Coefficient
  • Easily ductile
  • Resistant to atmospheric corrosion
  • Can be easily soldered and molded

CuNi40 constantan wire application

 

CuNi alloy wireis typically used in heating cables, fuses, resistors and various types of controllers, electric car controller, the instruments and meters, the integrated circuit, the sample electric current, the resistor. And low pressure resistance and so on. 


As a big manufacturer and exporter in China on the line of electric resistance alloy, we can supply all kinds of electric resistancealloy wire and strips (resistance steel wire and strips weiding wire)
 

 

PRODUCT APPLICATION

 

use of constantan

 

Constantan is used for the measurement of temperature. It is used for the formation of thermocouple, along with the wires of other metals such as copper, iron and chromel. It is especially used for resistance purpose since its resistance does not change much with the change in its temperature. It is used for DC current shunts. In the DC current shunts, the precision low value resistance wire is placed in series with the load in a direct current circuit, which is alreadycarrying a high current. It one measures the voltage drop; he can easily measure the current.
