Our magnetic segment is made of SrO·6Fe2O3 and other microelements by ceramic processing.
Strontium ferrite powders have been designed to produce all grades of hard ferrites. We will make high quality by adding proper additives into the powders. Our strict quality control system ensures that the quality is stable and reliable.
Product styles available: Arc, Segment.

Permenant Ferrite Magnets for sale
Ferrite Magnets' outstanding properties
1) High performance:
JC-Y3932; JC-Y3939; JC-Y4041; JC-Y4127; JC-Y4231; JC-Y3744; JC-Y3849; JC-Y4240 JC-Y4350 etc (The grade like JC-Y4350&JC-Y3849, JC-Y4240could meet requirements on strong power).
2) High working temperature:
The JC-Y4350 series with 4800-5150 OE super-high coercive force can replace NdFeB magnets with much lower price.
3) High consistency:
The Br and Hcj of surface magnetic field and magnetic flux can be controlled with +/-1%.
4) High Anti-corrosion:
The sale spray test and humid heat test of the high anti-corrosion coating could be more than 800 hours
5) Low weight loss
The average low weight loss is less than 10 mg/cm2 in 20 days.
Pros: Pretty strong hold between two of these blocks even if a couple of them by contacting the other one or plain iron. It's difficult to pull away them(easy to slide however).
Ferrite Magnet applications
Motor assemblies, step motor, DC motor, linear motor, speakers, and so on.
Also good for attaching thick stacks of paper to refrigerators etc or pinching papers or textiles together.
