Monel Alloy K500 ®

Monel Alloy K500 ® is a nickel-copper alloy which can be hardened through cold drawing and precipitation. With the elements of aluminium and titanium, Monel alloy K500 offers the excellent resistance to corrosion of Alloy 400; with elevated strength, hardness, erosion resistance and oxidation fatigue resistance. When compared to K400, K500 has shown to have a much higher tensile and yield strength.
