Cupro-Nickel
Copper-nickel alloys 90/10 and 70/30: the classic materials for seawater piping, condensers and heat exchangers, with natural biofouling resistance.
Cupro-Nickel grades
- Cupro-Nickel 90/10Cupro-nickel 90/10 (UNS C70600, CuNi10Fe1Mn) is a copper-nickel alloy with iron and manganese, the standard material for seawater piping and condenser tubes because of its corrosion and biofouling resistance.
- Cupro-Nickel 70/30Cupro-nickel 70/30 (UNS C71500, CuNi30Mn1Fe) has about 30% nickel, giving higher strength and better resistance to erosion, polluted seawater and ammonia than 90/10.
