90/10 Copper Nickel is uniquely qualified as an ideal candidate for piping systems in the ship-building industry due to its alloy properties, including low general corrosion rates in seawater, resistance to stress corrosion cracking due to ammonia in seawater, high resistance to crevice corrosion and stress corrosion due to chlorides, good pitting resistance, ready weldability, ease of fabrication and inherent resistance to biofouling.
