Monel Washers are mainly made from a nickel-copper alloy, typically consisting of 67% nickel and 33% copper, with small amounts of iron, manganese, and carbon added to boost mechanical strength and corrosion resistance. This unique composition gives them outstanding resistance to seawater, hydrofluoric acid, alkalis, and other harsh substances. Monel Washers boast a tensile strength of around 620 MPa, a yield strength of 275 MPa, and an elongation of 35%, ensuring exceptional mechanical stability. The alloy retains its toughness, ductility, and integrity even at high temperatures while effectively resisting stress corrosion cracking and embrittlement.
