These washers are primarily composed of a copper-nickel alloy, often with a small addition of iron and manganese, creating a material known for its exceptional resistance to corrosion, especially in seawater environments. This specific composition grants them impressive mechanical strength and ductility, allowing them to maintain a secure seal under significant pressure and vibration. They are tough, resilient, and designed to withstand the test of time, performing reliably where ordinary washers would quickly succumb to the elements.
