Material Notes:
A nickel-iron-chromium electrical-resistance alloy for use at operating temperatures up to 2010°F (1100°C). It contains rare-earth additions for increased oxidation resistance, especially under conditions of frequent switching or wide temperature fluctuations. The alloy has a relatively high temperature coefficient of resistance. Used for heating elements in domestic appliances and industrial equipment. Standard product forms are sheet, strip, and wire.Data provided by the manufacturer, Special Metals.
