Such Sheet or Plate is manufactured by hot or cold working, and annealed if required in order to produce a uniform wrought structure to meets the specified temper properties. Cupro Nickel Alloy with small amounts of iron and manganese improves corrosion resistance in high-velocity waters, including seawater. Cupro-Nickel are among the most attractive, durable and versatile copper alloys available. Offering unique properties such as excellent resistance to biological fouling, corrosion and stress corrosion cracking, these alloys are used in a range of applications from heat exchangers, ship components and condenser tubes of power plants to coinage and even touch surfaces on medical equipment.
