### **Product Introduction: Alloy X-750 / Inconel X-750 Foil & Shim Stock (UNS N07750)** #### **Overview** **Alloy X-750 Foil & Shim Stock** (commercially known as **Inconel® X-750 Foil & Shim**) represents the thin-gauge form of this premium nickel-chromium superalloy, precision-rolled to exacting thickness tolerances for specialized high-temperature applications. This product form combines the alloy's exceptional high-temperature strength, good corrosion resistance, and outstanding oxidation resistance with the versatility of thin, formable material. Inconel X-750 foil is particularly valued for its ability to be formed in the annealed condition and then precipitation-hardened to achieve high strength and thermal stability up to 700°C (1300°F) in final assemblies. The material's unique combination of properties makes it ideal for precision spacing, thermal management, sealing, and electrical applications in extreme environments where conventional materials would fail. --- #### **Chemical Composition** The chemical composition of Alloy X-750 Foil & Shim (UNS N07750) maintains the same rigorous standards as other product forms: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 -
