The Copper Nickel 90/10 Coil is made up of 90% copper and 10% nickel, with small amounts of iron and manganese added to boost its strength and corrosion resistance. This alloy is particularly well-suited for marine environments due to its outstanding resistance to seawater corrosion and biofouling. 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 while being able to withstand high temperatures. Its toughness and resistance to erosion and stress corrosion cracking ensure it performs reliably in harsh conditions.
