Monel K500 Tube Fittings are crafted from a precipitation-hardened nickel-copper alloy, primarily consisting of about 63% nickel and 30% copper, with added aluminum and titanium to boost strength. This alloy showcases remarkable mechanical properties, featuring a tensile strength of 110–140 ksi (758–965 MPa) and a yield strength of 75–100 ksi (517–689 MPa), along with good elongation and hardness. Monel K500 retains its high strength and corrosion resistance even in freezing temperatures, making it suitable for marine, chemical, and high-stress environments where mechanical reliability is essential.
