Material
Copper Nickel C71500 (70/30, CW354H)
CNC-machined Copper Nickel C71500 (70/30) is a high-strength copper-nickel alloy with excellent seawater corrosion and erosion resistance, suited to faster-flowing and more demanding marine service than 90/10.

About
C71500 (70/30 cupronickel, CW354H) is about 30% nickel, which raises strength and corrosion resistance compared with 90/10 but lowers conductivity and ductility.
It keeps good resistance to biofouling, is non-magnetic when annealed, and machines poorly.
Copper Nickel C71500 is a strong choice for high-velocity seawater piping, condensers, and demanding marine fittings.
