Material Notes:
A nickel-iron-chromium electrical-resistance alloy for use at operating temperatures up to 1920°F (1050°C). It is similar to BRIGHTRAY alloy F but with rare-earth additions for greater resistance to oxidation under conditions of frequent switching or wide temperature fluctuations. The alloy has a high temperature coefficient of resistance. Used for heating elements in domestic appliances and industrial equipment. The standard product form is wire.Data provided by the manufacturer, Special Metals.
