### **Product Introduction: Alloy X-750 / Inconel X-750 Strip (UNS N07750)** #### **Overview** **Alloy X-750 Strip** (commercially known as **Inconel® X-750 Strip**) is a precision-rolled nickel-chromium alloy supplied in thin, narrow coil form, offering an exceptional combination of high strength, good corrosion resistance, and excellent oxidation resistance up to 700°C (1300°F). This precipitation-hardenable superalloy strip maintains outstanding mechanical properties under high-temperature conditions and provides superior spring properties, making it particularly suitable for high-temperature spring applications, precision components, and electrical applications in aerospace, nuclear, and industrial sectors. The strip product undergoes sophisticated cold rolling and controlled heat treatment processes to achieve exact gauge control, superior surface finish, and consistent mechanical properties essential for demanding precision applications. --- #### **Chemical Composition** The chemical composition of Alloy X-750 Strip (UNS N07750) is carefully balanced for optimal performance: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 -
