Tape, a circle, a wire 80-nm
Relevance
Precision soft magnetic alloy 80-nm after heat treatment, slow cooling becomes the minimum deviation of the characteristics under normal climatic temperatures. Used to compact cores of transformers, chokes operating in weak magnetic fields; contactless relay small thickness (up to 0.02-mm) cores of magnetic amplifiers and pulse transformers.
properties
It features a maximum permeability, minimal coercive force. saturation induction 0.65−0.75 T in weak fields. According to GOST 693−74 19 ≤ coercive force of 4 kA / m. It is characterized by a high level of magnetic initial permeability can be magnetized to saturation in weak fields. Such iron-based alloys, and cobalt-doped nickel.
Characteristic
Soft magnetic materials are made from low-carbon steels based on high purity ferromagnetic iron, electrical low coercitive alloys of iron or iron-nickel-based composite powder and ferromagnetic materials. Such alloys are melted in a special induction furnaces, and then subjected to pull the shoes ingots or rental.
Using
Production of transformer cores, microphones, computer memory components, magnetic circuits operating in the marine environment, magnetic antenna, stators and rotors of electric motors. 80-nm Fusion is most relevant for the magnetic cores of the magnetic alternating field in the electronic, electrical industry, automation and remote control systems, measuring and computing. This alloy is widely used in the construction of transformers and motors,
