Introduction

BRIGHTRAY alloys are composed of nickel and chromium. These alloys were first developed by Henry Wiggins and Co, Birmingham. Originally the alloy contained 80% nickel and 20% chromium. The alloy is capable of operating at elevated temperatures of 1050°C (1922°F) and resist corrosion due to oxidation.

BRIGHTRAY alloy S is known as an electrical-resistance alloy, capable of operating continuously at temperatures up to 1150°C (2100°F). Characteristics of this alloy are similar to those of BRIGHTRAY alloy C. BRIGHTRAY alloy exhibits good resistance to corrosion in oxidizing, reducing and neutral environments. The alloy has a low temperature coefficient of resistance. This alloy is available in the form of wire and strip.

This datasheet will look into the chemical composition, properties and applications of BRIGHTRAY alloy B.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
