**Technical Datasheet: Alloy 75 (Haynes 75 / UNS N06075) Wire** **1. Introduction** Alloy 75 (commercially known as **Haynes 75** and standardized as **UNS N06075**) is a solid-solution strengthened nickel-chromium-tungsten alloy specifically engineered for extreme high-temperature service. In **wire** form, this material combines exceptional high-temperature strength with outstanding oxidation resistance, making it ideal for applications requiring continuous performance at temperatures up to 1200°C (2200°F). The wire product form offers excellent drawability, consistent dimensional control, and superior surface quality for both structural and functional applications in demanding thermal environments. **2.
