Inconel X750 wire is a premium nickel-chromium alloy engineered for high-strength applications requiring excellent corrosion resistance and thermal stability. At DLX, we provide Inconel X750 wire optimized for aerospace springs, high-strength fasteners, turbine components, and other high-performance applications.
Inconel X750 is a precipitation-hardened nickel-chromium alloy. Nickel forms the corrosion-resistant base, chromium enhances oxidation resistance, and niobium/tantalum strengthens the alloy through precipitation hardening. This combination provides outstanding tensile strength, creep resistance, and stability under high-stress and high-temperature conditions.
