    Description

    Nickel NP2 is used: for the production of semi-finished products (strips, sheets, strips, pipes, wire, drawn (5−40 mm) and hot rolled (42−90 mm) bars); elements of instrumentation and engineering; joints of sheet structures with a thickness of 2.0 to 6.0 mm, working with radioactive environment; as a cladding layer in the manufacture of hot-rolled dual-layer corrosion-resistant sheets; tape thickness of 0.05−2.0 mm, used in electronics and other industries.

    Ni is the basis.
    According to GOST 492-2006, the total mass fraction of impurities is ≤ 0.50%. Due to the mass fraction of nickel, the mass fraction of cobalt in the amount of ≤ 0.20% is allowed. Upon agreement of the manufacturer with the consumer, the mass fraction of zinc in the amount of ≤ 0.020% is allowed.
