Description

Nickel NP3 is used: for the production of semi-finished products (wire, bands, sheets and strips, drawn (5−40 mm) and hot rolled (42−90 mm) bars); elements of instrumentation and engineering; joints of sheet structures with thickness more than 6.0 mm, working with radioactive environment; as the active layer of the thermostatic bimetallic, is used for making sensitive to the temperature change of the elements of control and measuring instruments and apparatus; tape thickness of 0.05−2.0 mm, used in electronics and other industries.
