Magnetic grid scale performance

Magnetic scale ulnar body may meet certain requirements of the hard magnetic alloy. Can also be coated with a layer of hard magnetic alloy magnetic material. Made of magnetic scale on the magnetic properties of hard magnetic alloys should have the following requirements:

1) good magnetic material should have a larger remanence and coercivity, ie material hysteresis loop should be bigger than the fat.

2) good magnetic name tags homogeneity of the magnetic material more uniform as possible to ensure that after the recording magnetic remanence equal in magnitude, otherwise it will affect the accuracy of the magnetic grid.

3) good magnetic stability of materials for the magnetic remanence after the time there should not extend as soon weaken performance.

4) good mechanical properties of the material should have high mechanical strength, hardness and abrasion resistance, easy to machine and less susceptible to external changes in temperature and humidity.

5) to ensure a certain degree of frequency characteristics of the residual magnetization in a record on the request of the desired frequency (wavelength) of the wave.

The hard magnetic Drawer Magnet alloy used Cu-Ni-Fe alloy or Fe-Cr-Co alloy; conventional magnetic coating composition is Ni, Co, P.
