Product Description
CuNi44 NC050 Nickel Alloy Wire Valves Precision Resistance Parts Material
Resistance heating wire and resistance wire,Common Name:CuNi44,NC50.
NC050 is a copper-nickel alloy (Cu56Ni44 alloy) with low resistivity for use at temperatures up to 400°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.
