The Copper Nickel 90/10 Fasteners are made up of 90% copper and 10% nickel, with a touch of iron and manganese added to boost their strength and resistance to seawater corrosion. This alloy is fantastic at resisting biofouling, stress corrosion, and erosion in marine environments. It has a tensile strength of around 275 MPa, a yield strength of 105 MPa, and an elongation of 30%. Plus, it maintains good thermal and electrical conductivity and performs admirably under high temperatures and pressures. Its exceptional toughness and resistance to hydrogen embrittlement make it a great choice for both freshwater and seawater applications.
