Material Notes:
A nickel-chromium electrical-resistance alloy for use at operating temperatures up to 2100°F (1150°C). It contains rare-earth additions for increased oxidation resistance, especially under conditions of frequent switching or wide temperature fluctuations. The alloy has a low temperature coefficient of resistance, making it suitable for control resistors. Used for heating elements in domestic appliances and industrial equipment. The standard product form is wire.Data provided by the manufacturer, Special Metals.
