Characteristic

  and useage

It is the electric resistance alloy with the copper, manganese, nickel as the essential component. It is a superior precision resistor material with the characteristics of high electronic resistivity, very small resistance temperature coefficient, low Thermal EMF vs. Copper E  and  long-term stability. It is mainly applied in manufacturing heater resistances and resistance elements of standard resistor, precision instrument and so on.
