Monel Tube Fittings are made from Monel 400 or Monel K500 alloys, primarily composed of nickel (≈67%) and copper (≈30%), with small amounts of iron and manganese. This composition offers outstanding resistance to seawater, acids, and alkalis, along with excellent mechanical strength and toughness. Monel K500, being age-hardened, provides higher tensile and yield strength while maintaining corrosion resistance. These fittings exhibit excellent fatigue resistance, ductility, and stability across a wide temperature range, ensuring durability and consistent performance in both high-pressure and corrosive industrial environments.
