Introduction
BRIGHTRAY alloys are nickel-chromium alloys with a higher proportion of nickel. This alloy was first developed at Henry Wiggin and Co, Birmingham. BRIGHTRAY alloys are characterized by good corrosion resistance and ability to function even at elevated temperatures of 1050°C (1922°F).
BRIGHTRAY alloy C is known as electrical resistance alloy, and it consists of nickel and chromium as the principal elements. Rare-earth elements are added to the alloy in order to enhance its oxidation resistance even at frequently fluctuating temperatures. This alloy is able to function even at temperatures of 1150°C (2100°F). The temperature coefficient of resistance of this alloy is low. The standard form of this alloy is wire.
This datasheet will look into the chemical composition, properties and applications of BRIGHTRAY alloy C.
