2J85 is a new type of Fe-Cr-Co deformed permanent magnet alloy, characterized by its machinability and the ability to undergo cold deformation processing. The performance of 2J85 is equivalent to that of cast aluminum nickel cobalt magnets, and it also has good ductility in the quenched state. Its cobalt content is low, its magnetic properties are relatively high, and its processing technology is relatively simple. It is mainly used in fields such as electricity, sound, sensors, instruments, and automobiles. Alloys can produce various magnetic components through processing methods such as drawing, rolling, and stamping.
2J85 alloy produces various magnetic components through processing methods such as drawing, rolling, and stamping.
Metal magnetic materials are roughly divided into two categories: high permeability soft magnetic alloys and high coercivity hard magnetic alloys. The semi hard magnetic material with performance between soft and hard magnetic materials has a coercivity Hc of 0.79-19.89kA/m and a residual Br of over 1T.
The development of semi hard magnetic materials can be mainly attributed to two aspects. Firstly, permanent magnet alloys with coercivity Hc=3.97~19.89kA/m and residual Br>800 mT are used in hysteresis motors, which have advantages such as fast starting, excellent synchronous characteristics, and low noise. They are currently widely used.
Due to the increasing demand for materials and the increasing variety of hysteresis motors; Secondly, in the automatic control system, materials with low coercivity Hc and high residual Br are required for iron spring relays, door lock relays, etc; Some other electronic instruments also widely use this type of material with intermediate properties, and the amount and variety are constantly expanding, thus promoting the development of this type of semi hard magnetic material with intermediate properties.
