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.
