**Product Data Sheet: Alloy B / Brightray B High-Temperature Alloy Foil & Shim Stock** **1. Product Overview** **Brightray B** (Alloy B) in foil and shim form represents the ultimate in precision-engineered high-temperature materials. Produced through sophisticated rolling and finishing processes, these ultra-thin gauges maintain all the exceptional high-temperature properties of the alloy while offering unparalleled flexibility and conformability. Brightray B foil and shim materials are specifically designed for applications where minimal thickness, precise dimensions, and reliable performance in extreme thermal environments are critical requirements. The material develops the same protective chromium oxide scale as thicker forms, ensuring outstanding oxidation resistance even in these delicate configurations. **2.
