When it comes to Copper Nickel washers, they are generally crafted from either 90/10 (90% copper, 10% nickel) or 70/30 (70% copper, 30% nickel) alloys. These alloys contain small amounts of iron and manganese, which boost their mechanical strength and resistance to corrosion and biofouling. Depending on the grade, Copper Nickel washers offer impressive tensile strength ranging from 310 to 500 MPa, along with strong thermal stability and ductility. They hold up well in high-moisture, saline, and mildly acidic environments, making them perfect for long-term use in demanding situations that require tough, corrosion-resistant washers.
