FERRY ALLOY

没有此类产品
产品描述
A copper-nickel alloy used mainly for its electrical properties. It has mediumrange electrical resistivity and a very low temperature coefficient of resistance (TCR). The low TCR makes the alloy useful for wire-wound precision resistors having operating temperatures up to 750°F (400°C). A reproducible electromotive force against copper makes the alloy suitable for thermocouples and thermocouple compensating leads.
STANDARD PRODUCT FORMS
Strip and wire.
