Aerospace Monel K-500 fasteners
Aerospace Monel K-500 fasteners are high-performance connectors made from Monel K-500 nickel-copper alloy. They are designed for the harsh environments in aerospace. Compared to Monel 400, they have added aluminum and titanium. This makes them stronger, harder, and more corrosion-resistant through age hardening. They also keep good ductility and fatigue resistance. These fasteners include bolts, screws, nuts, and washers. They meet the needs of high-load and high-reliability assembly.
Aerospace Monel K-500 fasteners are used in aircraft engines, fuel systems, spacecraft structures, and offshore platforms. They can stand extreme temperatures, salt spray, and chemical corrosion. They are also good for high-load and lightweight applications like satellite brackets, nuclear facilities, and petrochemical equipment. They ensure long-term reliability and low maintenance. They are key connectors in high-end industries.
Features of Aerospace Monel K-500 fasteners
Excellent corrosion resistance: Aerospace Monel K-500 fasteners resist stress corrosion cracking and pitting in seawater, acidic media, and high-temperature steam. They perform much better than regular stainless steel.
High strength and light weight: After age hardening, the tensile strength can reach over 1100 MPa. The density is low (about 8.44 g/cm³), which is good for aircraft parts that need to be light.
Wide temperature adaptability: Aerospace Monel K-500 fasteners keep mechanical stability from -200°C to +480°C. They are suitable for the extreme temperatures in spacecraft.
Non-magnetic and electrically conductive: Aerospace Monel K-500 fasteners have no magnetism and conduct electricity well. They are often used in electronic equipment shielding or lightning strike protection structures.

Applications of Aerospace Monel K-500 fasteners
Aviation: Aerospace Monel K-500 fasteners are used in engine compartments, fuel systems, and hydraulic lines. They resist corrosion from fuel vapors and salt spray.
Aerospace and marine: Aerospace Monel K-500 fasteners are used in satellite brackets and offshore platform fasteners. They keep working well even when exposed to the marine atmosphere for a long time.
Energy and chemical: Aerospace Monel K-500 fasteners are used in oil drilling platforms and nuclear reactor auxiliary equipment. They can handle hydrogen sulfide and high-temperature, high-pressure conditions.
