Aerospace Incoloy 825 fasteners
Aerospace Incoloy 825 fasteners are made from the high-performance nickel-iron-chromium alloy Incoloy 825. They are designed for extreme environments. Incoloy 825 contains nickel (38-46%), chromium (19.5-23.5%), molybdenum (2.5-3.5%) and copper (1.5-3.0%). It has excellent corrosion resistance and high-temperature strength. These fasteners include bolts, screws, nuts and washers. They are precision machined and heat treated strictly. This ensures their reliability in the aerospace field.
Aerospace Incoloy 825 fasteners are widely used in aerospace (engines, fuel systems), petrochemical (acid-resistant pipes, nuclear power equipment) and marine engineering (ships, offshore platforms). With excellent corrosion resistance, high-temperature strength and fatigue resistance, they ensure reliability and long life in extreme environments. They are key fastening solutions for harsh working conditions.
Features of Aerospace Incoloy 825 fasteners
Excellent Corrosion Resistance: Aerospace Incoloy 825 fasteners can resist sulfuric acid, phosphoric acid and chloride stress corrosion cracking. They are suitable for highly corrosive environments.
High-Temperature Performance: Aerospace Incoloy 825 fasteners keep high mechanical strength and oxidation resistance at high temperatures. They have a wide working temperature range from -200°C to +540°C.
Superior Mechanical Properties: Aerospace Incoloy 825 fasteners have high strength, good toughness and fatigue resistance. They are suitable for dynamic loads and vibrations.
Machining and Welding: Aerospace Incoloy 825 fasteners can be machined and welded by conventional methods. This makes it easy to make complex fasteners.

Applications of Aerospace Incoloy 825 fasteners
Aerospace: Aerospace Incoloy 825 fasteners are used in aircraft engine parts, fuel systems and high-temperature pipe connections. They resist high-temperature gases and corrosive media.
