Copper Nickel Washers are top-notch sealing and load-bearing components celebrated for their remarkable resistance to corrosion, strength, and durability, especially in marine and high-temperature settings. Made from copper-nickel alloys like Cu-Ni 90/10 or 70/30, these washers excel at resisting seawater, biofouling, and stress corrosion cracking. Their impressive thermal stability and anti-erosion features make them perfect for tough industrial tasks. You’ll find Copper Nickel Washers commonly used in shipbuilding, desalination plants, offshore engineering, heat exchangers, and power generation systems. Their reliability and long lifespan make them a go-to choice for fastening assemblies that face harsh, corrosive conditions.
Copper Nickel Washers are generally made of copper combined with 10% or 30% nickel, plus small amounts of iron and manganese to boost strength and corrosion resistance. These alloys are known for their excellent resistance to seawater corrosion, erosion, and hydrogen embrittlement. In terms of mechanics, Copper Nickel Washers offer good tensile strength, moderate hardness, and high ductility, which helps them endure vibration and mechanical stress. They maintain stability at high temperatures and provide great thermal conductivity. This blend of corrosion resistance, toughness, and dimensional stability makes them ideal for critical marine and industrial fastening applications.
