Información del producto

  • Descripción de los productos


Constantan alloy is a resistance alloy that based on copper nickel. The resistivity is slightly higher than that of manganese copper, and it has good oxidation resistance and processability. Due to its high thermoelectric potential on copper, this alloy is limited to the production of precision resistors for AC use, sliding resistors, starting and adjusting rheostats, and resistance strain gauges for use below 200 ℃ at room temperature. It can also be used as low-temperature electric heating elements below 100 ℃.
