**Technical Datasheet: Alloy 75 (Haynes 75 / UNS N06075) Foil & Shim** **1. Introduction** Alloy 75 (commercially known as **Haynes 75** and standardized as **UNS N06075**) is a premium nickel-chromium-tungsten alloy engineered for extreme high-temperature applications. In **foil and shim** forms, this material delivers exceptional performance in precision applications requiring minimal thickness, superior oxidation resistance, and reliable performance at temperatures up to 1200°C (2200°F). These ultra-thin product forms are essential for thermal management, sealing, and spacing in high-temperature environments where conventional materials would fail. **2.
