4.Characteristics

BRIGHTRAY alloy F is a nickel-iron-chromium electrical-resistance alloy for use at temperatures  up to 1920°F (1050°C) under
 continuous operating conditions.  Its high iron content and relatively low level of nickel make it particularly resistant to internal 
oxidation in  atmospheres that alternate between oxidizing and reducing or carburizing. The alloy has a high temperature 
coefficient of resistance.

5.Applications

Heating elements in industrial furnaces.
