**Technical Datasheet: Alloy 75 (Haynes 75 / UNS N06075) Strip** **1. Introduction** Alloy 75 (commercially known as **Haynes 75** and standardized as **UNS N06075**) is a premium nickel-chromium-tungsten alloy specifically engineered for high-temperature applications requiring precision-formed components. In **strip** form, this material combines exceptional elevated temperature strength with superior oxidation resistance, while offering precise dimensional tolerances and excellent surface quality. The strip product form is particularly suited for manufacturing intricate components through stamping, forming, and deep drawing processes that must maintain performance at temperatures up to 1200°C (2200°F). **2.
