**Product Data Sheet: Alloy B / Brightray B High-Temperature Alloy Fittings** **1. Product Overview** **Brightray B** (Alloy B) is a premium nickel-chromium (80/20) alloy specifically engineered for extreme temperature applications. This datasheet details the **fittings** manufactured from this superior material, which are precision-engineered components designed for connecting and directing flow in high-temperature systems. Brightray B fittings maintain exceptional oxidation resistance, structural integrity, and thermal stability, making them ideal for critical connections in furnace systems, thermal processing equipment, and corrosive industrial environments. These fittings develop a continuous, self-healing chromium oxide (Cr₂O₃) scale when exposed to high temperatures, providing reliable, long-term protection against oxidative degradation and ensuring system integrity under thermal cycling conditions. **2.
