Technical characteristics

Precision alloy 80NM is a soft-magnetic alloy that does not exceed coercive force 4kA/m by induction. It also possesses a small coercive force at saturation induction 0,65−0,75 Т in weak fields and very high magnetic inductive capacity. After a heat treating with gradual cooling (starting from +600°С), it characterizes by small changes of characteristics in a climatic temperature range. Soft-magnetic alloys can magnetize to saturation in weak fields. Except for iron, a composition consists of cobalt, nickel, molybdenum. Extra-pure ferromagnet iron, low-coercive precision alloys on a iron-nickel or ferrum basis, low-carbon electrotechnical steels (unalloyed, siliceous) relate to this type of soft-magnetic materials. Ferromagnet, ferrimagnet, powdered, compositional materials also belong to this category. Such alloys are melted into special metallurgic furnaces with a further forging or ingot rolling.

Soft-magnetic alloys are widely used for manufacturing the transformer cores, microphones, components of computer memory, magnetic antennas, details for electric machines, magnet cores. All those are intended to be exploited in sea water. Alloy 80NM is used in electric machine industry, transformers, radio engineering, magnet cores of a variable magnetic field, an electrotechnical sphere of industry, automation systems, teleautomatics and computationally measuring equipment.
