N4 (Ni201/N02201) is a low-carbon pure nickel grade with Ni + Co ≥99.9%. It combines strong corrosion resistance with stable electrical and thermal performance for demanding industrial service. The low carbon level helps prevent graphitization embrittlement during prolonged high-temperature use, while the material remains ductile and easy to process into plate, strip, bar, tube and wire.
