CuNi19 NC025 Nickel Alloy Rod Strip Wire Valves Precision Resistance Parts Material
OhmAlloy025 (Resistance heating wire and resistance wire)
(Common Name:CuNi19,NC25)
OhmAlloy025 is a copper-nickel alloy (Cu81Ni19 alloy) with low resistivity for use at temperatures up to 300°C.
The ductility of copper-nickel alloy is very good, so it can be used in shipbuilding and petrochemical industry. Some electrical appliances and meters also use the ductility of copper-nickel alloys to manufacture parts. Copper-nickel alloys are mostly used in industrial production. Some valves and some precision resistance parts will be made of copper-nickel alloys.
