Copper Nickel 90/10 sheets and plates
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 sheet and plate are generally known for their good corrosion resistance, excellent machinability, and outstanding thermal and electrical conductivity.

Properties
Cupro nickel 90/10 sheet and cupro nickel 90/10 plate are made to upsurge its resistance to general corrosion, impingement corrosion and erosion resulting from the stormy movement of water comprising silt flowing and air bubbles at a superior velocity.
