Excellent property of ferrite magnets
1) High performance:
JC-Y3932; JC-Y3939; JC-Y4041; JC-Y4127; JC-Y4231; JC-Y3744;
JC-Y3849; JC-Y4240JC-Y4350, etc. Require).
2) High working temperature:
JC-Y4350 series has 4800-5150 OE ultra-high coercivity, which can
replace NdFeB magnets at a lower price.
3) High consistency:
Br and Hcj of surface magnetic field and flux can be controlled
within +/-1%.
4) High corrosion resistance:
Sales spray test and damp heat test of high anti-corrosion coatings
can exceed 800 hours
5) Low weight loss
The average low weight loss is less than 10mg/cm2 in 20 days.
Pros: Fairly strong even if two of the blocks are held between two
of them by contacting the other or plain iron. They are difficult
to pull apart (easy to slide though).
Ferrite Magnet Applications
Motor components, stepper motors, DC motors, linear motors,
speakers and more.
Also great for stacking thick sheets of paper on top of
refrigerators etc., or sandwiching paper or textiles together.
