Copper Nickel 90/10 Flat

Copper Nickel 90/10 Flat

Copper Nickel 90/10 is a copper nickel alloy that contains small but important additions of iron and manganese to enhance overall strength and corrosion resistance. Copper-nickel alloys flat are generally known for their good corrosion resistance, excellent machinability, and outstanding thermal and electrical conductivity.

90/10 alloy offers designers and specifiers excellent resistance to stress corrosion, erosion, and biofouling in seawater and brackish water, excellent fabrication and welding properties, a high resistance to hydrogen embrittlement and the retention of mechanical properties down to cryogenic temperature.

Application

Cupro Nickel 90/10 flats or (UNS C70600) are used in power steering tube, brake lines, condenser flats, pressure vessels and distiller tubes. Because of their unique useful properties, Cupro Nickel 90/10 flat and flats are specified for marine engineering applications, such as in shipbuilding and repair, desalination plants, offshore oil and gas structures and power generation.
