Electrovacuum nickel alloys N4 (Ni201) and N6 (Ni200) exhibit excellent workability, superior mechanical and physical properties, high melting points, strong corrosion resistance, and adequate thermal strength.

They are primarily used in the fabrication of electrovacuum devices and electronic components, as well as in the textile industry for producing nets for various applications.
