Nichrome Round Wire and Nichrome Ribbon Wire
Nichrome Wire 80/20
NickelChrome Alloys containing long life additions which make it eminently suitable for applications such as nichrome resistance wire, subject to, frequent switching and wide temperature fluctuations. It may be used at operating temperatures up to 1150 C. A relatively low temperature coefficient of resistance with a high resistivity makes it suitable for control resistors.
Inventory shapes/ sizes
