    Product Description

    C70200 CuNi2.2

    The copper nickel alloy is the low resistivity alloy used at temperature range up to 300°C (570°F). The alloy is mainly used in heating cables in electric pillows and blankets. The medium resistivity and low temperature coefficient of resistance also make these alloys ideal for control resistors and thermocouples.
