The Copper Nickel washers are a type of alloy made up of primarily copper and nickel with specific compositions ranging from a ratio of 70% copper to 30% nickel to 90% copper to 10% nickel which also include trace amounts of Iron and Manganese for increased material strength and corrosion resistance. These unique compositions help give Copper Nickel Washers the highest level of marine and offshore environments protection from seawater, chloride corrosion and Biofouling of all other materials on the market. Copper Nickel washers are moderately to very high tensile strength depending on alloy type (310-550 MPa) and yield strength (120-250 MPa) and have good ductility (Elongation 35%-40%) and medium hardness (80-150 HB) that create a very long lasting, reliable product that withstands harsh conditions.
