These coils are mainly made of copper mixed with nickel, along with a dash of iron and manganese to boost their strength and corrosion resistance. This alloy boasts fantastic mechanical properties, including solid tensile strength, high ductility, and a strong resistance to stress corrosion cracking. They stay stable across a wide range of temperatures and have low magnetic permeability. Their thermal conductivity ensures efficient heat transfer, and the nickel content significantly improves their resistance to oxidation and erosion, especially in high-velocity fluid situations, making them dependable for continuous and demanding operations.
