general characteristics
Mark 36KNM relates to corrosion-resistant soft magnetic precision alloys with low coercive force and high magnetic field induction in the mild, moderate intensity. In the structure, except for iron (metal core) has a cobalt (35−36%), nickel (21−22%), Mo (2.8−3.2%). Dopants act manganese and silicon. A distinctive feature of 36KNM alloy is improved resistance to rust, as well as a sufficiently high level of induction in weak magnetic fields. The alloy is widely used in the production of magnetic wire operating in sea water or high humidity conditions.
