Introduction
Nickel-chromium alloys with relatively high nickel content are known as BRIGHTRAY alloys. These alloys were originally developed at Henry Wiggins and Co at Birmingham. Original BRIGHTRAY alloys contained 80% of nickel and 20% of chromium. These alloys are characterized by good corrosion resistance and ability to function at elevated temperatures.
BRIGHTRAY alloy F is an electrical-resistance alloy composed of nickel-chromium-iron. It is capable of operating continuously at temperatures of 1050°C (1920°F). The high iron content and low nickel content of the alloy make it alloy capable of resisting internal oxidation in environments that fluctuate between oxidizing and reducing. The temperature co-efficient of this alloy is high. This alloy is available in the form of sheet and strip.
This datasheet will look into the chemical composition, properties and applications of BRIGHTRAY alloy B.
